Question

Consider the system:

Line 1: x - y = 9
Line 2: 3x + 3y = 3
The ordered pair (3, -6) is a solution to:
Line 1
Line 2
The System of Equations

Answer 1

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

Answer 2

Line 1

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
