How much is Michael earning per hour?
Answer provided by our tutors
y = 10x + 50
The amount of money in the account to start with is $50, which acts as the y-intecept. It is also the value of y (money in account) when the number of hours worked (x) is 0.
Michael earns $10 per hour, which is the slope of the linear equation.
