Question

What is the slope of the line that passes through the points (-9, 10) and (21, 15)?

Write your answer in simplest form.

Answer 1

1/6

Explanation:

(-9, 10) (21, 15)

`slope = (y_(2)-y_(1) )/(x_(2)-x_(1) )`

`m = (15-10)/(21-(-9))`

`m=(5)/(30) = (1)/(6)`

Answer 2

1/6 or 1.666667

Explanation:

(y2-y1)/(x2-x1)

(15-10)/(21- -9) = 1/6
