{(-1,2), (0,5), (5,0), (2,-1)}
Answer: C
Step-by-step explanation:
The X value repeats itself
Step-by-step explanation: In order for a function not to be a relation,
each x-coordinate must correspond to more than one y-coordinate.
Notice that in third relation, the 1 pairs with a 3
in one case and it pairs with a 7 in the other case.
Since each x-coordinate pairs with more than one y-coordinate,
this relation is not a function but the other ones are functions.

Why is 18:3 and 6:1 equivalent ratios
Answer:
Because if you multiply 6 three times, it comes out to be 18.
So basically, 6 x 3 = 18
To be sure, 18 ÷ 6 = 3
So, 18:3 = 6:1
18:3 and 6:1 are equivalent ratios because those are equivalent fractions.
What is the ratio?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
or [tex]\dfrac{a}{b}[/tex]
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Explanation;
If we get the factors of the first ratio, we will see that;
18: 6 and 3, and 18 and 1
3: 3 and 1
Hence, if we display the ratios in fractions;
18/3 = 6/1
And then we write them in factors, we will get;
3x6/3x1 = 6/1
Simplifying;
3/3 x 6/1 = 2/1 x 3/1 = 1/6
Therefore, 18:3 and 6:1 are equivalent ratios.
