Write an equation for the line parallel to the given line that contains C(4,8);y=-3x+4

1 answer:

6 0

Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20

The answer is y = -3x + 20
