Aconjecture and the flowchart proof used to prove the conjecture are shown.

given: s is the midpoint of rt. us≅rs

prove: △stu is an isosceles triangle

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.
