Answer and Explanation 1 We are asked to graph y = 1 3x−2 y = 1 3 x − 2 To do this, we will find ordered pairs, graph them on the Cartesian plane, and then connect them on a straight lineSo, we could talk of a 'straight line graph' for which 'as x increases, y steadily increases' (Figure 73a) or for which 'as x increases, y steadily decreases' (Figure 73b) The term 'steadily' is a rather informal term but it gives a good sense of what is happening Figure 73 Graphs with straight lines (a) (b) The relationships shown in 'curved graphs' are more complexInteractive, free online graphing calculator from GeoGebra graph functions, plot data, drag sliders, and much more!

Line graph for y x
Line graph for y x-The lines( ) function adds information to a graph It can not produce a graph on its own Usually it follows a plot(x, y) command that produces a graph By default, plot( ) plots the (x,y) points Use the type="n" option in the plot( ) command, to create the graph with axes, titles, etc, but without plotting the points (To practice creating line charts with this lines( ) function, try thisGiven the function {eq}y = \frac{5}{3}x {/eq}, we need to obtain its graph First, we find the ordered pairs by evaluating the function in values for the variable {eq}x {/eq}

XY Graphs & Gradients One way of drawing different xy graphs is to make the line steeper or shallower than y=x The green line y=2x above is steeper than the line y=x because each value of y on the line is twice that of x The blue line y=05x above is shallower than the line y=x because each value of y on the line is half that of xA line has equation y = x – 3 (a) Using x values from –1 to 4, work out the missing values in the table below (b) Plot the points on the graph below and draw a straight line through the points Exercises Work out the answers to the questions below and fill in the boxes Click on the button to find out whether you have answered correctly If you are right then will appear and you shouldB is easy just see where the line crosses the Y axis m (the Slope) needs some calculation m = Change in Y Change in X Knowing this we can work out the equation of a straight line Example 1 m = 2 1 = 2 b = 1 (value of y when x=0) Putting that into y
To graph the inequality y = x 6, we first graph the equation y = x 6 shown in Figure 713 Notice that (3, 3), (3, 2), (3, 1), (3, 0), and so on, associated with the points that are on or below the line, are all solutions of the inequality y = x 6, whereas (3,4), (3, 5), and (3,6), associated with points above the line are not solutions of the inequality In fact, all ordered pairsThe line graph consists of a horizontal xaxis and a vertical yaxis Most line graphs only deal with positive number values, so these axes typically intersect near the bottom of the yaxis and the left end of the xaxis The point at which the axes intersect is always (0, 0) Each axis is labeled with a data type For example, the xaxis could be days, weeks, quarters, or years, while the yA line graph is set up as a vertical axis (the Y axis) and a horizontal axis (the X axis), forming a grid One of the two factors is measured on the Y axis and the other is measured on the X axis To create the graph a point is placed on the grid where the value of the X variable and the value of theY variable intersect A line is then drawn to connect the points on the graph, moving from left
The simple way to graph y = x1 is to generate at least two points, put those on your graph paper and draw a straight line through them Here's how you geneate the required points Use your equation, y = x1 and choose an integer for x, say x=2, and substitute this into your equation to find the corresponding value of y y = 2 1 y = 1 So your first point has coordinates of (2, 1) NowWe will go to the Charts group and select the X and Y Scatter chart In the dropdown menu, we will choose the second option Figure 4 – How to plot points in excel Our Chart will look like this Figure 5This is the graph of \(y = 3x 1\) Sketching straight line graphs If you recognise that the equation is that of a straight line graph, then it is not actually necessary to create a table of values

To graph y = x 1 we begin by locating the ordered pairs obtained above, as shown in Figure 6(a) All the points of this graph appear to lie on a straight line, as in Figure 6(b) This straight line is the graph of y = x 1 It can be shown that every equation of the form ax by = c has a straight line as its graph Although just two points are needed to determine a line, it is a good idea y = 5x 7 3x 2y = 1 Plot families of exponential and reciprocal graphs For example y = 2 x, y = 3 x, y = 4 x y = 1÷x, y = 2÷x, y = 3÷x, Reduce a given linear equation in two variables to the standard form y = mx c;On this problem We want a graph Y equals 1/3 X plus two Now, thankfully, it's already in soap intercept Foreign Force So why intercept here is to that's where we start and then our slope is 1/3 So from our Y intercept, we go up one over three or we don't down One left three and I would draw the line through those points And so that's what the line Y equals 1/3 x plus two is going to look

Another way of drawing different xy graphs is to make the line higher or lower than y=x The green line y=x3 above is higher up than the line y=x because each value of y on the line is 3 more than that of x However, the blue line y=x2 above is lower down than the line y=x because each value of y on the line is 2 less that of x The number after x in the formula tells us how high the line The equation y = − x can be written in slope intercept form as y = − 1 1 x 0 making the y intercept at (0,0) and the slope − 1 1 Begin by graphing the y intercept at the origin (0,0) and then use the slope down 1 for 1 and over 1 to map the remaining points Answer link See a solution process below First, solve for two points which solve the equation and plot these points First Point For x = 0 y = 0 5 y = 5 or (0, 5) Second Point For x = 5 y = 5 5 y = 0 or (5, 0) We can next plot the two points on the coordinate plane graph{(x^2(y5)^075)((x5)^2y^075)=0 14, 14, 7, 7} Now, we can draw a straight line through the two points to graph
