You can put this solution on YOUR website! A line in slope intercept form, has as its slope.
So in your case,
Interpret?
Without more information, hard to say.
It is negative, so the value of V decreases as t increases.
Other than that, not much you can say.
You can put this solution on YOUR website! This is in the form y=mx+b, so the slope is -150.
V(t) is usually velocity as a function of time, and the equation suggests that for unit t, the velocity decreases 150 units.
