Given : Joseph plots the speed of his car and time on a scatter plot.
The equation for the line of best fit on his scatter plot is y = -15x + 60, where x is the time in hours and y is the speed in miles/hour.
To Find : Which statement describes the situation correctly
Solution:
As the time increases the speed decreases.
y = -15x + 60
at x = 0
y = 60 ( maximum )
at x = 4
y = 0 ( minimum )
As the time increases speed decreases
With initial speed 60 and final speed at rest after 4 unit time
