Question

What is the slope of the line that passes through the points (4,9) and (1, 6)?​

Answer 1

The answer is 1

Explanation:

to calculate the slope m use the

gradient formula

m = y2 - y1/x2 - x1

let (x1, y1) = (4, 9) and (x2, y2) = (1, 6)

⇒ m = 6 - 9/1 - 4 = -3/-3 = 1.

Answer 2

m = Δy / Δx

x₁=4
x₂=1

y₁=9
y₂=6


9-6
----- =
4-1

m = 1
