Question

What is the equation on the graphed line (2,6) (-4,-6) answer in slope intercept form

Answer 1

y = 2x + 2

Explanation:

→ Find the gradient

`(-6-6)/(-4-2) =(-12)/(-6) =2`

→ Rewrite into y = mx + c format

y = 2x + c

→ Substitute in a coordinate pair

6 = 4 + c ∴ c = 2

→ Rewrite into y = mx + c format

y = 2x + 2
