Find the slope intercept form of the line whose slope is 3 and that passes through the point (-5,12)

Question

What is the equation of the line

Answer 1

There are 2 ways to solve these.

(y - y₁) = m(x - x₁)

y - 12 = 3(x - (-5))

y - 12 = 3x + 15

y = 3x + 27

orrrr...

y = mx + b

12 = 3(-5) + b

12 = -15 + b

b = 27

y = 3x + 27
