Answer:
infinite solutions along the line -3x+y = 6
Step-by-step explanation:
9x -3y = -18
-3x + y = 6
Multiply the second equation by 3
3( -3x+y) = 3*6
-9x +3y = 18
Add this to the first equation
9x -3y = -18
-9x +3y = 18
------------------------
0 + 0 = 0
This means it is the same line which means there are infinite solutions along the line -3x+y = 6
