Chang is driving to New York City.
The distance travel by Chang show the linear relationship with the time.
The graph of the relation between the distance left and time is given as;
Such, that the slope of the line is given as;
Slope = - 0.9 minutes
The standrad form of the linear equation is : y = mx + b, where m is the slope.
Since, Chang has 37 miles remaining after 33 minutes of driving.
i.e. at x = 33, y = 37
y = mx + b
37 = (-0.9)(33) + b
b = 66.7
Thus, the equation of the graph will be;
y = (-0.9)x + 66.7
Now, for the distance left after 41 minutes of travelling
Substitute x = 41 in the equation of the graph;
y = -0.9x + 66.7
y = (-0.9)(41) + 66.7
y = 29.8
Thus, 29.8 miles will be left after 41 miles of driving.
Answer : 29,8 miles will be left after 41 miles of driving.
