Question

What is the slope of the line that passes through the points (4, 9)(4,9) and (7, 18) ?(7,18)? Write your answer in simplest form.

Answer 1

Slope = 3

Explanation:

Calculate using slope formula:
`m = (y2-y1)/(x2-x1)`

`(x1, y1) = (4, 9)` and
`(x2, y2) = (7, 18)`

`m = (18 - 9)/(7 - 4) = (9)/(3) = 3`
