Question

Line R is represented by the following equation: x + y = 2

Which equation completes the system that is satisfied by the solution (1, 1)? (4 points)

2x + y = 2
4x − 2y = 2
2x − 2y = 2
x + y = 4

Answer 1

so for the point x=1 and y=1

Answer 2

so plug that in into the equations

Answer 3

and see which one is true

Answer 4

for it to be true you'll end up with something like1=1 or 2=2 or 3=3
