Question

The system of equations 2y = 14 - 2x and y=-x+ 7 is

graphed. What is the solution to the system of equations?
no solution
(0,-7)

Answer 1

Infinitely many solutions

Explanation:

2y=14-2x

y=-x+7

------------

2(-x+7)=14-2x

-2x+14=14-2x

-2x-(-2x)=14-14

-2x+2x=0

0=0

infinitely many solutions
