Question

Find the equation of the line.
Use exact numbers.

Answer 1

y = 4x + - 9

Explanation:

(3, 3), (4, 7)

(x₁, y₁) (x₂, y₂)

y₂ - y₁ 7 - 3 4

m = ------------ = ------------ = ------- = 4

x₂ - x₁ 4 - 3 1

y - y₁ = m(x - x₁)

y - 3 = 4(x - 3)

y - 3 = 4x - 12

+3 +3

----------------------

y = 4x - 9

I hope this helps!
