Unless K is defined, this problem doesn’t make sense...even if we divide over k then k would eventually equal nothing (not zero)
This equation is in slope-intercept form of y = mx + b form.
The m represented by the coefficient of the x term
represents the slope and b represents the y-intercept.
So our y-intercept is -4 and we can write this as the ordered pair (0, -4).

Answer:
29.5 hours
Step-by-step explanation:
Amityville to Denton is 1625 miles.
Since we know that Sarah drives at 55 mph we can divide 1625/55 and get 29.45454... and I assume that they want it rounded so it will be around 29.5 hours
