Question

A line is given by the formula y=x+2. Determine which of the following points belong to its graph: M(0, 2),N(1, 3), A(−1, 1), B(−4.7, −2.7), C(−2 1/2 , 1/2 ).

Answer 1

Answer: M, N, A, B

Explanation:

Plug in x-value (add 2 to x-coordinate) and see if it matches the y-value. Only C isn’t on the graph because -2.5+2=-0.5, not positive 0.5.
