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

Start with y + 4 = 3(x + 2).
Expand: y + 4 = 3x + 6.
Subtract 4: y = 3x + 2.

So the correct choice is y = 3x + 2.
