    ok, well, to find the slope between two coordinates, you use this formula for two coordinates (x1,y1) and (x2, y2): 1. slope = (y2 - y1)/(x2 - x1)

    so in the case of your problem: x1 = -2, x2 = -1, y1 = 7, and y2 = 2

    so stick those into the slope formula and you will have your answer

    It would be (-2-7) (-1-2) right?

    well, the slope is one number, that basically represents "for every x coordinate I move to the right, how many y coordinates do I move up?"

    so the slope = (y2 - y1)/(x2 - x1) = (2 - 7)/ (-1 - (-2))

    or sorry did not mess up, the answer is -5/1 = -5

    through (2,1) slope =-3/2 How do I write the slope intercept form of the equation?
