Find the slope of the line that contains (-2, - 2) and (-10, - 9).

A) 8/7

B) 11/12

C) 12/11

D) 7/8

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

7

8

= 0.875

θ =

arctan (ΔY) + 180°

ΔX

= 221.18592516571°

ΔX = - 10 - - 2 = - 8

ΔY = - 9 - - 2 = - 7

Distance (d) = √ΔX2 + ΔY2 = √113 = 10.630145812735

Equation of the line:

y = 0.875x - 0.25

or

y =

7 x

8

- 1

4

When x=0, y = - 0.25

When y=0, x = 0.28571428571429
