For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:
m: It's the slope
b: It is the cut-off point with the y axis
On the other hand we have that if two lines are perpendicular, then the product of their slopes is -1. So:

The given line is:

So we have:

We find 

So, a line perpendicular to the one given is of the form:

We substitute the given point to find "b":

Finally we have:

In point-slope form we have:

What i think is that u should but it as an equation first re read the problem
it says that he score rose up to 725 so her equation would be around the first box and in says on how much she would pay and all that i hope i helped
Answer:
We have x^2 + 4x^2 = 5 ( we use substitution);
Then, 5x^2 = 5;
x^2 = 1;
x = +1 or x = -1;
Finally, y = +2 or y = -2.
