What are the coordinates of p?

THIRD OPTION.

Step-by-step explanation:

Given the trapezoid in the figure, you know the coordinates of  two points:

(0,c) and (a,b)

You can observe that the point (a,b) and the point P have the same x-coordinate, because both points are "a" units from the origin.

Then, the x-coordinate of P is:

Now, in order to find the y-coordinate of the point P, you need to remember that when the line touches the x-axis, the value of "y" is equal to zero. Therefore, the y-coordinates of the point P is:

Then the answer is:

mx+89b(-98)nb
