Question

Find the slope of a line that goes through the points (-3, -4) and (1, 1).

-4/5
5/4
-5/4
4/5

Answer 1

5/4

Explanation:

Slope m = (y2-y1)/(x2-x1)

m = (1 - -4)/(1 - -3) = (1 + 4)/(1 + 3) = 5/4

Answer 2

slope =
`(5)/(4)`

Explanation:

Calculate the slope m using the slope formula

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

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

m =
`(1-(-4))/(1-(-3))` =
`(1+4)/(1+3)` =
`(5)/(4)`
