Question

What is the slope of the line that passes through (4,-9) and
(1,3)?

Answer 1

`m=-4`; the slope is -4

Explanation:

`slope=(rise)/(run) =(y^2-y^1)/(x^2-x^1)`

coordinates: (4,-9) (1,3)

`(3-(-9))/(1-4)=(-12)/(-3) =-4`

= -4 is your answer

hope this helped

Answer 2

slope = - 4

Explanation:

calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (4, - 9 ) and (x₂, y₂ ) = 1, 3 )

m =
`(3-(-9))/(1-4)` =
`(3+9)/(-3)` =
`(12)/(-3)` = - 4
