Having trouble with this question. can someone me.

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

First function - y = 4x + 5
It is in the form mx + c

Slope ,m = 4

For second function
y - y1 / x - x1 = 10 - 6/ 3 -1 = 4/2 = 2
Slope = 2

So comparing them, the correct answer is B

Hope This Helps You!

Could you make it more clear?
