Revise how to plot a linear equation graph. Learn how to read x and y coordinates from a graph in this BBC Bitesize maths KS3 guide.

Figure 1a. Graph for y = 3x + 4. Figure 1b. Graph for y = 2x 2 - 3x + 4.. Figure 1c. Graph for y = 0.6x 3 + 2x 2 - 3x + 4.. In school I also had the x- and y-axes represent something, such as age ...

Now make a graph. Be sure it is an "x-y scatter" and not "line" - see how good Open Office is? They even use the dumb names that Excel uses for types of graphs. Only plot the X and Y values.
