Answer:
7. Option B:40 is the correct answer.
8. Option D: y = 40x+75 is the correct answer.
Step-by-step explanation:
Given that:
Charges per hour = $40
Fee charged by repairman = $75
x = number of hours
y = total fee
According to given statement;
y = 40x+75
The standard equation is
y = mx + b
On comparing;
Slope of the line is given by m, therefore
Slope = m = 40
Hence,
7. Option B:40 is the correct answer.
8. Option D: y = 40x+75 is the correct answer.
