The tables represent two linear functions in a system. x y negative 4 26 negative 2 18 0 10 2 2 x y negative 4 14 negative 2 8 0 2 2 negative 4 What is the solution to this system?

Answer
A
8 comma negative 22
B
1 comma 0
C
8 comma 26
D
1 comma 6

Explanation

In the first table, y decreases by 8 when x increases by 2, so its slope is −4 and its equation is y = −4x + 10. In the second table, y decreases by 6 when x increases by 2, so its slope is −3 and its equation is y = −3x + 2. Set the equations equal: −4x + 10 = −3x + 2, which gives x = 8; substituting gives y = −22. The solution is choice B, (8, −22).
