Question

write the equation of a line parallel to the given line but passing through the given point. y=2x-1; (2, -2)

Answer 1

I think you messed up on the equation. Where's the x?

Answer 2

Alright.
y=2x-1
Plug in the numbers.
-2=2(2)-b
(Because you're trying to find a new y intersection to have a parallel line with the equation, the slope stays the same.)
-2=4-b
-6=-b
6=b
y=2x-6
