    I think the first 'pair' should be 'line' ? Do you know the formula for the slope of a line given two points?

    \[Slope = {y_2 - y_1 \over x_2 - x_1}\] Where (x1,y1) is one point and (x2,y2) is the other point.

    this is what I was doing, (-4,-10)(-5,-11) Subtract 10 from -4, to get -14. (-14)(-5,-11) Subtract 11 from -5, to get -16. (-14)(-16) Multiply -14 by -16 to get 224. (224) Remove the parentheses around the expression 224. 224

    you want the change in y divided by the change in x. y starts at -10 and goes to -11 so it has changed -1. x starts at -4 and goes to -5 so it changes by -1. Then you have -1/-1=1

    I'm pretty sure this is some kind of math troll. He's trying to multiply the x part of the point to the y part, then multiply those two products together.
