Question

Which set of points would result in a slope of ?

(2, 8) and (1, 4)
(8, 2) and (1, 4)
(8, 2) and (4, 1)
(2, 8) and (4, 1)

Answer 1

(2, 8) and (1, 4) would result in a slope of -4.

To find the slope, you can use the formula:

slope = (change in y) / (change in x)

In this case, the change in y is 4 - 8 = -4, and the change in x is 1 - 2 = -1. So:

slope = (-4) / (-1) = 4

But since the second point has a smaller x-coordinate than the first point, the slope is actually negative. So the correct answer is (2, 8) and (1, 4).
