Answer:
The equation for babysitting can be written as y = 20x + 5, where y is the total cost and x is the number of hours.
The slope of the equation is 20, which represents the rate of change in the total cost (y) with respect to the number of hours (x).
The slope represents the rate at which the total cost changes for each unit change in the number of hours. In this case, for each hour of babysitting, the total cost increases by $20.
The y-intercept of the equation is 5, which represents the cost when x = 0, i.e. when there is no babysitting time.
The y-intercept represents the starting value of the total cost, in this case, the amount charged for babysitting even when there is no babysitting time.
