For function one, the slope is already in mx+b form. The coefficient to x is the slope, so it is four in this case. For the second function we calculate the slope using rise over run. The rise is change in y and run is change in x, so 4/2= 2 slope. Four is greater than two so it has the greater rate of change. The answer is B
Yes. I totally agree with that statement. 10/10
X= 103
180 - 65 = 115
X + 12 = 115
X = 115 - 12 = 103
just separate the ramge and domain
