Question

Find the slope of the line through the points (-4,6) and (8,4).

A.) -5/6
B.) -1/6
C.) -3/2
D.) -1/2

Answer 1

B) -1/6

Explanation:

y₂ - y₁ / x₂ - x₁

4-6 /8-(-4) = -2/12 = -1/6

Answer 2

The formula of a slope:

`m=(y_2-y_1)/(x_2-x_1)`

We have the points (-4, 6) and (8, 4). Substitute:

`m=(4-6)/(8-(-4))=(-2)/(12)=\boxed{-(1)/(6)}\to\boxed{B.)}`
