I need the answer to y=2x+2

Question

using the system of equations 

y=mx+b 

and is 3,6 a solution for y=3x-3 

and y=2x+2

Answer 1

Subtract y =2x + 2 from y =3x - 3
0 = x - 5
x=5,y=0 (5,0) is the intersection and the solution is the point (5,0)

 

 

 

Answer 2

Test the solution (3, 6) in each of the equations.

 

y = 2x + 2

6 = 2(3) + 2

6 = 6 + 2              (3, 6) does not solve the equation. No need to proceed.
