Question

Find the gradient of the line passing through (-2, 5) and (5, -5)

Answer 1

slope = -
`(10)/(7)`

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 2, 5 ) and (x₂, y₂ ) = (5, - 5 )

m =
`(-5-5)/(5-(-2))` =
`(-10)/(5+2)` = -
`(10)/(7)`
