Answer:
y = mx + b
Step-by-step explanation:
The reason is, x is always the hour, and m is the amount of money you earn in the hours.
Answer:
b = 40
Step-by-step explanation:
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair.
This situation can be described by an equation of the form y=mx+b , where
x = the time in hours
y = the cost in dollars.
What is the value of b in this equation?
A heater repairman charges $40 to visit a home, plus $70 per hour for the time he spends on the repair
Writing the above in an equation =
y = $70 × x + $40
y = 70x + 40
Therefore, the value of b in the expression = 40
Answer:
x= 4/5 or 0.8
Step-by-step explanation:
The answer is A because the perpendicular slope is the opposite reciprocal which would be positive x.
