Question

Find the equation of a line that is parallel to y = 2x + 3 and passes through (-1, -1).
A) y = 2x + 1
B) y = 2x + 3
C) y = 4x + 3
D) y

Answer 1

The answer is A) y=2x+1. When you use the equation y - y1 = m (x - x1) you get y + 1 = 2(x + 1). It simplifies to y + 1 = 2x + 2 and then to y= 2x + 1.
