Consider the system:

Line 2: 3x + 3y = 3
The ordered pair (3, -6) is a solution to:

Answer:

Line 1

Step-by-step explanation:

Since x=3 and y=-6, just plug those two values in both of the equations.

Line1: (3)-(-6)=9    This would be the answer

Line2: 3(3)+3(-6) = -9  This is the incorrect answer because it should 3

it’s line 1 because if you plug in the ordered pair given it will equal 9 :)
