Notice that the triangle is a right triangle, because of the right angle. By the Pythagorean Theorem,
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
. Then
![15^2+b^2=17^2\implies 225+b^2=289\implies b^2=64\implies b=8](https://tex.z-dn.net/?f=15%5E2%2Bb%5E2%3D17%5E2%5Cimplies%20225%2Bb%5E2%3D289%5Cimplies%20b%5E2%3D64%5Cimplies%20b%3D8)

15/15 or 1 is your answer.
Answer:
(2, 2 )
Step-by-step explanation:
To find a solution, choose any value for x, substitute into the equation and solve for y.
Choose x = 2, then
- 2 - 4y = - 10 ( add 2 to both sides )
- 4y = - 8 ( divide both sides by - 4 )
y = 2
Thus (2, 2 ) is a solution to the equation
