81x^6y^4 is the answer
Hope it help
It is useful because it helps you know how many faces the prism or pyramid has
<h3>
<u>Explanation</u></h3>

- Calculate the slope with two given coordinate by using rise over run.

These two coordinate points are part of the graph and can be used to find the slope.

Substitute the coordinate points in the formula.

Therefore, the slope is 2.
Rewrite the equation in slope-intercept.

- Calculate the y-intercept by substituting any given points in new rewritten equation.

I will be substituting these coordinate points in the equation.

Substitute x = 0 and y = 5 in the equation.

Therefore the y-intercept is (0,2).
Rewrite the equation.

Number of hours is x values and cost of service is y.
To find slope you have to find the change in y over the change in x.
We can use any points in the table to calculate this amount.
Eg, 3-5 hours and 125-175 dollars.
The difference in y values is $50 and the difference in hours is 2.
50/2=25
The slope is 25
