Given: the coordinates of triangle pqr are (0,0), q(2a,0), and r(2b,2c). prove: the line containing the midpoints of two sides of a triangle is parallel to the third scale.
as part of the proof find the midpoint of qr

a) (a-b, c)
b) (a+b, c)
c) (a, c)
d) (b, c)

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

x = 23.78
