Its asking you to substitute each value of x into the equation y=2x+2
so for x=-3 you would substitute it at y=2(-3)+2 which would give you the answer -4
i'll write out each answer so you can check your work
a=-4
b=0
c=4
d=6
hope this helps! if you're still confused please leave a comment and i can clarify my answer more :)
