Line R is represented by the following equation:

x + y = 2

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


A. 2x + y = 2
B. 4x – 2y = 2
C. 2x – 2y = 2
D. x + y = 4

Answer 1

plug in 1 for x and for y and see which one works
for example, not A because \(2+1=3\)

Answer 2

so is it D?

Answer 3

no \(1+1=2\) not 4

Answer 4

so none of the answers are possible
