Question

The points in the table lie on a line. Find the slope of the line.

Answer 1

4

Explanation:

slope = rise/run = (difference in y)/(difference in x)

Subtract any two y-coordinates.

-10 - 2 = -12

Now subtract the corresponding x-coordinates in the same order.

-2 - 1 = -3

slope = rise/run = (difference in y)/(difference in x)

slope = (-12)/(-3) = 4
