Question

Part A: Maria rented a coat at $285 for 3 days. If she rents the same coat for 6 days, she has to pay a total rent of $510.

Write an equation in the standard form to represent the total rent (y) that Maria has to pay for renting the coat for x days.

Part B: Write the equation obtained in Part A using function notation.

Part C: Describe the steps to graph the equation obtained above on the coordinate axes. Mention the labels on the axes and the intervals.

This cannot be determined, unless one assumes a model. Assuming a linear model, some fixed base cost, then a per day cost.
Costtotal=costperday*days + fixed
and you have two equations.
285=3x+f
510=6x+f

solving (double the first equation, then subtract it from the second
570=6x+2f
510=6x+f

60=fixed cost
and you solve for the per day cost, x.
