Anna is no more than 3 years older than 2 times jamie’s age. jamie is at least 14 and anna is at most 35. which system of linear inequalities can be used to find the possible ages of anna, a, and jamie, j?

In order for the function to be linear, what must m be and why? m = 22 because the rate of change is 1. m = 20 because the rate of change is 3. m = 22 because the rate of change is -1. m = 20 because the rate of change is -3.
