Question

What is the equation of the line that goes through (2, -1) and is parallel to y=
3x - 3?

Answer 1

y + 1 = 3 (x - 2) (the first option - A - in the list of possible answers)

Explanation:

Since the new line has to be parallel to y = 3 x - 3, then it has to have the SAME slope (3) and go through (2, -1). Therefore the slope-point general form has to be:

y - (-1) = 3 (x - 2)

y + 1 = 3 (x - 2)
