Question

What is the slope that passes through (4, 5) (9, 20)​

Answer 1

slope = 3

Explanation:

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (4, 5) and (x₂, y₂ ) = (9, 20)

m =
`(20-5)/(9-4)` =
`(15)/(5)` = 3

Answer 2

3

Explanation:

slope = y2-y1/x2-x1

slope = (20-5)/(9-4)

slope = 15/5 = 3
