Question

Find the slope of the line that passes through the points (2,-8) and (3,1)

Answer 1

m = 9

Explanation:

Slope of line that passes through two points:
`m=(y_2-y_1)/(x_2-x_1)`

(2, -8) ⇒ x₁ = 2, y₁ = -8

(3, 1) ⇒ x₂ = 3, y₂ = 1

`\bold{m=(1-(-8))/(2-2)=\frac{1+8}1=9}`

Answer 2

9

Explanation:

y2 -y1 = 1 -(-8) = 9

x2-x1 = 3-2 = 1

9/1

9
