I think it’s B, because it’s not adding or subtracting in a pattern
A. 2860
180 x 12 (months in a year) = $2160
$2160+700= $2860
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
5.3 or 5.30 it doesn't matter how many 0's you add
