Question

Write an equation of the line that passes through the given point and is parrel to the given line.

1. (-1,3) Y=2x+2
I'm thinking that you just plug in -1 and 3 for x and y.

So, 3=2(-1)+2
Correct?
Please help me. :)

Thank you

Answer 1

Nope: Y=mx+ b is the general form. Plug in (-1,3) to get
3=-m+b

Now parallel means the same slope (y=2x+2, slope 2)

-3=-2+b
b=-1

equation of line? y=2x-1

Thank you.
