City A and B temperatures y and x are related by the equation, y = 3x + 1. Use the relationship to complete the table of values for the temperature of the two cities.

A. m = -10, n = 5Correct
B. m = 10, n = 5
C. m = -13, n = 6
D. m = -11, n = 7

Explanation

The table values (x = 0 gives -1, x = 1 gives 2) fit y = 3x - 1. M = 3(-3) - 1 = -10 and N = 3(2) - 1 = 5.
