Does this set of ordered pairs represent a function? Why or why not. Don’t need a step to step just the answer

Scrat [10]

Answer:

D. Yes,because every x-value corresponds to exactly one y-value.

Step-by-step explanation:

The given ordered pairs are;

{ $(-5,-5),(-1,-2),(0,-2),(3,7),(8,9)$ }

We do not have the same x-value corresponding to more than one y-value.

We can see from the ordered pairs that every x-value corresponds to exactly one y-value.

Therefore the graph of this relation will pass the vertical line test.
