OpenStudy (itsbribro):

(3, –8), (4, 4)

OpenStudy (itsbribro):

A. Neither is a solution. B. Both are solutions. C. The first is a solution, but the second is not. D. The first is not a solution, but the second is.

OpenStudy (anonymous):

Both are solutions. You can plug the x and y coordinates into the equation to find the answer.

OpenStudy (itsbribro):

thank you can you help me with a couple more please?

OpenStudy (anonymous):
