What is the fastest way to graph an equation of a line?

Answer 1

Step 1: Solve for y so that your equation is in the form of y=mx+b

Step 2: your m value is your y- intercept. So put the point (0,m) on the graph

Step 3: your b value is your slope of the equation. If your b value is already a fraction then the numerator is your "rise" and the denominator is your "run." If your b value is not a fraction then just make it into one by putting a fraction bar and a 1 underneath it. Now starting from the first point you put, go up or down the amount of your "rise" and mark the point. Positive is up and negative is down. For example if your "rise" is -3 then go down three points from your y intercept. Now from your second point, go left or right depending on your "run" and make a point. Positive is right and negative is left. For example, if my "run" is 5 then I will move 5 right and make a point.

Step 4: Connect your first and third point with a straight line and extend the line. Put arrow heads on both ends of your line and that is your equation of a line on a graph.
