Question

What is the slope of a line passing through (-4,-5)
and (-2,-9)?

Answer 1

slope = - 2

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 4, - 5 ) and (x₂, y₂ ) = (- 2, - 9 )

m =
`(-9-(-5))/(-2-(-4))` =
`(-9+5)/(-2+4)` =
`(-4)/(2)` = - 2

Answer 2

Gradient
= (y2-y1)/(x2-x1)
= (-9-(-5))(-2-(-4))
= (-4)(2)
= -8
