7. C. y = 2x - 3
8. Both are correct
Explanation:
7. Multiply the x value by 2, then subtract three. You eill notice they all equal to the corresponding y value
8. Divide each value by 2, (the same as multiplying by one half ) then subtract 2 from the quotient. you will get the corresponding y value for both tables.
