Question

What is the slope of the line that passes through the points (7, -9) and (6, -11)? Write your answer in simplest form.

Answer 1

y = 2x - 23

The slope is 2

Explanation:

Slope (m)

m =
`(y_2-y_1)/(x_2-x_1)` =
`(-11-(-9))/(6 - 7)` =
`(-2)/(-1)` = 2

y = mx + b

y = 2x + b

(7, -9)

y = 2x + b

-9 = 2(7) + b

-9 = 14 + b

-14 -14

-23 = b

y = 2x - 23

Hope this helps!
