Question

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

Answer 1

Answer:

slope = - 2

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

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

m = $\frac{-9-(-5)}{-2-(-4)}$ = $\frac{-9+5}{-2+4}$ = $\frac{-4}{2}$ = - 2

Answer 2

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