Question

Write an equation for the line that contains the point (-2, 9) and is parallel to the line y = 2x + 6.
A. y = -(1/2)x + 8
B. y = 2x – 7
C. y = 2x + 11
D. y = 2x + 13

Answer 1

If the line is parallel, it has the same slope. So we can just plug in the given x and y values into the original equation.
9=2(-2)+b
9=-4+b
13=b
So the equation would be y=2x+13 so the answer is D.
