Find the x-intercept and the y-intercept: y=2x-2 Please show me how to do it!

Answer:

Ok, y=2x-2 is the slope of the line. the y axis is the same as zero on the x axis. so first, what you need to do is substitute 0 for x in the equation, then solve. you should get y=0-2. Therefore, the y-intercept is -2, the coordinates should be (0,-2). To find the x-intercept, simply plot your y intercept on a graph, and do rise over run (rise two, run one) from that point until you intercept the x-axis. the coordinates should be (1,0).

Think about slope intercept form. It’s y=mx+b, m is the slope and b is the y-intercept. So in your equation b is -2 and the slope is 2/1. So graph the y intercept and then use the slope until it passes through the x-axis. And remember, the x-axis is horizontal and the y-axis is vertical.
