Write an equation of the line that passes through (−4, −9) and is parallel to the line y=4x.

Question

An equation of the parallel line is y=

Answer 1

y=4x + b where b= the y intercept

plug in the point to solve for b

-9=4(-4) + b

b = -9 +16 = 7

the equation is y=4x+7. that's parallel to y=4x and goes through (-4,-9)
