Use the scenario to answer the question.
Zada is paid an hourly rate, as well as a bonus, each day. Her hourly rate is $12 per hour. When she works 4 hours, she earns a total of $68.
Which equation, in point-slope form, correctly represents Zada's pay in dollars, y, when she works x hours?
y−4=12(x−68)
y+68=12(x+4)
y−68=12(x−4)
y+4=12(x+68)
