Ineed quick with two math questions, 98 points. graph the system of equations on your graph paper to answer the question. {y=x+2 y=−x+8 {3x−8y=29 3x+y=−2 which ordered pair is the best estimate for the solution to the system? (0.5, −3.5) (0.75, −2.25) (0, −3.75) (0, −2) what is the solution for this system of equations?

Which statement explains how you could use coordinate geometry to prove the opposite sides of a quadrilateral are congruent? a. use the slope formula to prove the slopes of the opposite sides are the same. b. use the slope formula to prove the slopes of the opposite sides are opposite reciprocals. c. use the distance formula to prove the lengths of the opposite sides are the same. d. use the distance formula to prove the midpoints of the opposite sides are the same.
