Question

Madeline needs to find the slope of the line that passes through the points (9, 12) and (7,4) she sets up the following work​

Answer 1

4

Explanation:

The slope of the line passing through two given points:
`m=(y_2-y_1)/(x_2-x_1)`

(9, 12) ⇒ x₁ = 9, y₁ = 12

(7, 4) ⇒ x₂ = 7, y₂ = 4

So, the slope:

`m=(4-12)/(7-9)=(-8)/(-2)=4`
