Answer 1

The slope is
`- (2)/(7)`

_

Explanation:

☆Remember:
`m =  (y_2 - y_1)/(x_2 - x_1)`

---

☆We need to find the slope . So just plug in according to the slope formula!

`m =  (9 - 7)/(2- 9) = ( \: \: 2)/( - 7) = - (2)/(7)`

Answer 2

Explanation:

Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)

Slope of line passing through (9, 7) and (2, 9) = (9-7)/(2-9) = -2/7
