Question

Emelina wrote the equation of a line in point-slope form as shown below.

(y + 4) = 3 (x + 2)

What is Emelina’s equation in slope-intercept form?
y = 3x + 2
y = 3x +10
y = 3x – 4
y = 3x – 10

Answer 1

you'll need to solve the equation for y

starting with (y + 4) = 3 (x + 2)

distribute the 3 across the parentheses

then subtract 4 from each side

combine like terms
