Answer: The total area that he is painting is equal to 52m^2, The area that is given is the slope (8m^2/h) and the initial value of y(x) when x = 3 hours.

Step-by-step explanation:

The rate is 8 m^2 per hour. This means that in one hour, Hiro paints 8 m^2.

We know that he has 28 m^2 left to paint.

then we have that:

Y(3hours) = 28m^2

Then, we initially had a total area of:

Y(0) = 28m^2 + 3*8m^2 = 52 m^2

Where the thing i did is add the area he has left and the area he painted in the 3 hour he was painting.

The total area of the room is 52m^2
