B. seven minutes - because that is when the slope of the line is flat, which means he isn't moving.
If you mean the m^3=105, then m^6 will be
![( \sqrt[3]{105}) ^6](https://tex.z-dn.net/?f=%28%20%5Csqrt%5B3%5D%7B105%7D%29%20%5E6)
which is 105^2 which is
11025
= (3/8) (16x + - 24)
=(3/8) (16x) +(3/8)(-24)
=6x - 9
y = mx + b
where m is the slope and b is the y-intercept.
Here, the slope is -3/2 and the y-intercept is 5.
y = -3/2x + 5
