Answer:
y = 2x + 3 and y = x + 4
Explanation:
the first equation:
y = -3x - 6
(5) =-3(1) - 6
5 = 3-6
5≠-3
second equation:
y = 2x + 3
(5) = 2(1) + 3
5 = 2 + 3
5 = 5
third equation:
y = -7x + 1
(5) = -7(1) + 1
5 = -7 + 1
5 ≠ -6
fourth equation:
y = x + 4
(5) = 1 + 4
last equation:
y = -2x - 9
(5) = -2(1) - 9
5 = -2 - 9
5 ≠ -11
