Question

What is the distance from X to Y?

Answer 1

***Use Pythagorean Theorem***

- Draw a line to connect them, and make it into a triangle to the y and x axis.

- count how many squares are on the outside of the lines.

- use this formula: a^2+b^2=c^2

- c^2 is what the distance that your looking for.....

- 9^2 +12^2= c^2

- 81+144=225

- square root it= 15

Answer=

B. 15 units

Answer 2

Answer:

Step-by-step explanation:

To find the distance between two points, $(A, B)$ and $(C, D)$, you can use the following distance formula:

$distance = \sqrt{(A - C)^{2} + (B - D)^{2}}$

Plugging in the points from the problem, you'll get the following:

$\sqrt{(0 - 9)^{2} + (6 - (-6))^{2}}$

$\sqrt{(-9)^{2} + (12)^{2}}$

$\sqrt{81 + 144}$

$\sqrt{225}$

$15$
