She is incorrect, her statement comes with no solution.
Rational. Since it’s reappearing multiple times in a pattern, and not random numbers bunched together
Select the correct answer. Which relation is a function? A. {(2, 3), (1, 5), (2, 7)} B. {(-1, 5), (-2, 6), (-3, 7)} C. {(11, 9),

Answer:
Choice B represents a function
Step-by-step explanation:
For a relation to be a function, each x input should yield exactly one y output. Going by this definition, the relation given by alternative A is not a function since the x input 2 yields two different values of y. For alternative C, 11 yields 9 and 5 as the outputs hence contradicting the definition of a function. For alternative D, the value 3 yields two different y values.
UHH......duh
the numbers that go in 0-5 plot those numbers in that area continue that way and build up :)

It's an isosceles triangle 45° - 45° - 90°, therefore y = 5.
In that triangle, sides are in proportion 1 : 1 : √2.
Therefore we have x = 5√2.
<h3>Answer: B. x = 5√2, y = 5</h3>
Other method.
You can use the Pythagorean theorem:
x² = 5² + 5²
x² = 25 + 25
x² = 2 · 25
x = √(25 · 2)
x = √25 · √2
x = 5√2
<h3>Answer: B. x = 5√2, y = 5</h3>
