Question

What is the slope of the line that passes through the points (1,1) and (9,7)?

5/4
4/3
4/5
3/4

Answer 1

It's 3/4, simple enough just do delta y over delta x

Answer 2

slope =
`(3)/(4)`

Explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (9, 7)

m =
`(7-1)/(9-1)` =
`(6)/(8)` =
`(3)/(4)`
