Select the equation of the line parallel to the equation y = -2x - 7 that passes through the point (3, 1).
motikmotik

Formula of the line

y=mx+b.

For parallel line slope m is the same, so m= -2.

y=-2x+b.

We need to find b,using the point (3,1).

1= - 2*3+b

b=7

y = -2x +7

Answer is A. y = -2x +7.
