Which pair of points tells you the relation is NOT a function? {(1, 4), (8, 4), (3, 1), (1, 0), (6, 3)}
answers:
(1, 4) and (1, 0)

(1, 4) and (6, 3)

(1, 4) and (8, 4)

(1, 4) and (3, 1)

(1, 4) and (1, 0)

Step-by-step explanation:

for a function each input has one output we cant have a function if there are two of the same inputs 1 and 1 or 2 and 2 that have two different outputs

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

both equations and proportions are better.
