do you have some graph paper?
pick any value for x, and calculate y. The easiest value to use is x=0. Then y=3. So, the point (0,3) is on the graph.
For y, if you pick and even value, you will have a fraction for x, so pick any odd value, say, y=1. Then x=1, and (1,1) is on the graph.
Plot those two points on the graph paper, and connect them with a line. All done, except for labeling stuff.
You could have picked lots of other values for x and y, but they'd all have to be on the same line -- any two points on the line will do to get started.
Graph the linear function y=-2x+3
How do I work this out?
