The system Px = Qy = R and Tx + Uy =V has the solution (2,9), where P, Q, R, T, U and V are not = to 0. Select all systems of equations that have the same solution.
a. Px + Qy = R
(P + T)x + (Q + U)y = R + V
b. Px + Qy = R
(P +2T)x +Q + 2U)y = R- 2V
c. (T - P)x = (U - Q)y = V - R
Tx + Uy = V
d (T - P)x +(Q + U)y = V - R
Tx + Uy = V

Match the following terms with their definitions. 1. bisector of a segment ray ba and ray bc are opposite rays if a, b, and c are collinear and b (the endpoint of both rays) is between a and c. 2. opposite rays a ray, , is the set of points beginning at point a and going infinitely in the direction of point b. 3. collinear points a line or segment that intersects the segment at its midpoint. 4. betweenness of points a set of two or more points all on the same line. 5. ray the distance between the endpoints of a segment. 6. space point b is between a and c if a, b, and c are collinear and the equation ab + bc = ac is true, where ab, bc, and ac are the distances between points a and b, b and c, and a and c, respectively. 7. midpoint of a segment a set of two or more points all on the same plane. 8. coplanar points the point on a segment that divides the segment into two equal segments. 9. length of a segment the set of all possible points. 10. line segment the set of two different endpoints and all points between them.
