Answer: C) (1,0.80) represents the unit rate. E) (25,20) represents the price of a necklace with 25 beads
Step-by-step explanation:
(1, 0.80) represents the unit rate.
(25, 20) represents the price of a necklace with 25 beads.
= unit rate → 
= 0.80; 
= 0.80; 
= 0.80
Point (1, r) → (1, 0.80) represents the unit rate.
25(0.80) = 20; thus, (25, 20) represents the price of 25 beads.

Hello!
A function is that y only has 1 solution for every x
-3x + 8 = y is a function because it only has one y value for every x
y = x^2 + 3 is a function because it has only one y value for every x
y^2 = x is not a function because it has two y values for x = 4
Hope this helps!
