Slope formula
m = y₂- y₁/ x₂- x₁
m = - 2 - 2 / 10 - 8
m = - 4 / 2
m = - 2
- - - - - - - - -
Slope intercept formula
y = mx + b
2 = - 2(8) + b
2 = - 16 + b
2 + 16 = 16 + b - 16
18 = b
- - - - - -
y = -2x + 18

The slope would be -2. Considering x1 = 8, x2 = 10, y1 = 2 and y2 = -2, the slope will be (y2 - y1)/(x2 - x1).

use y2-y1/x2-x1 plug in the x and y coordinates for the first equation and the second. the result will be the slope
