Answer:
2x-y=-1
Step-by-step explanation:
y + 9 = 2(x + 5)
y + 9 = 2x + 10 [distribute]
y = 2x + 1 [subtract 9 from both sides]
y - 2x = 1 [subtract 2x from both sides]
-2x + y = 1 [put x first]
2x - y = -1 [multiply by -1 to make x coefficient positive]
Answer:
C. No, because one x-value corresponds to two different y-values
Step-by-step explanation:
An x-value cannot have two y-values. Hope this helps!
