The equation that show the relationship between Anna earning and time worked is y = 8.5h.
<h3>
Linear equation</h3>
Linear equation is in the form:
y = mx + b
where m is the rate of change, b is the y intercept and y, x are variables.
Let y represent Anna earnings for working h hours.
Since she charges $8.50 per hour to babysit. Hence:
y = 8.5h
The equation that show the relationship between Anna earning and time worked is y = 8.5h.
