A triangle PQR has its vertices at P (7, 6), Q (-1, -2), and R (-7, 4).

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

no solution

step-by-step explanation:

there is not enough information in the problem to solve.
