thank you
Answer by rapaljer(4671) (Show Source): You can put this solution on YOUR website!

Therefore
y=y
, which is a quadratic equation. Solve by setting it equal to zero:

Substitute back into either equation, usually the simplest one is best!
y = 2x +4
y = 2(1) + 4
y = 6

There is only one point of intersection, (1, 6) .

Just for fun, let's check by graphing:
