Question

5) Find the slope of the line that passes through (2,6) and (-7,8).

Answer 1

slope = -
`(2)/(9)`

Explanation:

Calculate the slope m using the slope formula

m =
`(y_(2)-y_(1) )/(x_(2)-x_(1) )`

with (x₁, y₁ ) = (2, 6) and (x₂, y₂ ) = (- 7, 8)

m =
`(8-6)/(-7-2)` =
`(2)/(-9)` = -
`(2)/(9)`
