Which statement is true of points on a coordinate grid? A.
A negative y-axis coordinate indicates a point in quadrant I or quadrant IV.

B.
A coordinate pair in which both numbers are negative represents a point in quadrant II.

C.
Changing signs on the x-coordinate of a point moves it to the quadrant across the x-axis.

D.
The signs on each number of the coordinate pair determine which quadrant contains that point, even if the values of the numbers are not known.

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.
