Question

Find the slope of the line that passes through the pair of points.

(-4, 1), (5, 4)

A
13

B
−13

C
-3

D
3

Answer 1

slope =
`(1)/(3)`

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (- 4, 1 ) and (x₂, y₂ ) = (5, 4 )

m =
`(4-1)/(5-(-4))` =
`(3)/(5+4)` =
`(3)/(9)` =
`(1)/(3)`
