This is the line graph for Y=-5
hope this helps!
5x + 2y = 13
x + 2y = 9
Subtract :- ( note that 2y - 2y = 0):-
4x + 0 = 4
x = 1
From 2nd equation plug in x = 1
1 + 2y = 9
2y = 8
y = 4
Solution to this equation is x=1,y=4
2x + y = 7
5x - y = 14
Adding eliminates the y terms because y + -y = 0 :-
7x + 0 = 21
7x = 21
x = 3
Plug x=3 into second equation:-
5(3) - y = 14
y = 15-14 = 1
solution is x =3, y = 1
