Taylor, remember that the equation of a line is y = mx +b, where m is the slope and b is the y-intercept.
Start with your first point on the y-axis at -2. Your slope is 1/2 (rise/run), so go up 1 and over 2 for your next point. Keep going with this and you'll find your points.
Another way to find your y-values is to plug in the x's you have. y = 1/2(2) - 2 = 1 - 2 = -1, so your first point is (2,-1). This should show up on your graph, as well.
What do you get when you plug in the 0? Your answer should be your first point on your graph, since along the y-axis, x = 0.
Hope this helps!
