Answer 1

line R: 2x+2y=18 subtract 2x from both sides and you'll get 2y=-2x+18 and then divide it by 2 and you'll get y=-x+9
line M: x+y=9 subtract x from both sides and you'll get y=-x+9
and I think its C

Answer 2

Solve by using the process of elimination.
To get the second equation to equal the first equation, multiply it by 2.

2(x+y=9) = 2x+2y=18
2x+2y=18 = 2x+2y=18

Answer 3

These equations both equal the same line. Do they have one solution, no solution, or infinitely many solutions?

Answer 4

Yes.
