Line $a$ is parallel to line $y=2x+4$ and passes through the point $(2,5)$. What is the y-intercept of line $a$?
Since line A is parallel to line y=2x+4, line A must have the same slope which is two(2).
Plug in (2,5) for x and y respectively
5=2(2)+b, 5=4+b, b=1
Thus, the y-intercept of line A is one(1).
Thanks, tertre !!!!
