step by step
Hello!
We can put the x values in and see if we get y
Option 1:
Set A: y = 4x - 2
Do the first values
y = 4(-1) - 2
y = -4 - 2
y = -6
Look at the next one to be sure
y = 4(1) - 2
y = 4 - 2
y = 2
So the set A equation is correct we can look at set be now
y = x + 4
y = -5 + 4
y = -1
Try the next one to be sure
y = -2 + 4
y = 2
So the set B equation is also correct
The answer is the first one
Hope this helps!
