Question

Find the slope of the line that passes through the points (9, -2) and (4, 3)

Answer 1

-x aka -1

Explanation:

x1 y1 x2 y2

9 -2 4 3

m= y2 - y1/x2 - x1

m = 3 + 2/4 - 9

(The "-" sign turned positive because it is negative times negative)

5/-5

Simplify: 5/-5 = -1 = -x

The slope of this line is -x
