Answer:
The distance was 225 miles when be began driving. The change in Milan's distance from Seattle for each hour he drives is -60.
Explanation:
Consider the provided equation.
225 - 60x = y
Where x is the time and y is distance.
For part (A):
When she begins the drive, x = 0.
Substitute the value of x in the provided equation.
y = 225 - 60(0)
y = 225
Hence, the distance was 225 miles when be began driving.
Part (B)
The slope intercept form is: y = mx + c
Where m is the slope and c is the y intercept.
By comparing the provided equation with the slope intercept form it can be conclude that the slope is -60 or the rate of change of distance with respect to x is -60
The change for every hour is the slope of the equation, which is - 60.
Hence, the change in Milan's distance from Seattle for each hour he drives is -60.
