A

Step-by-step explanation:

If you were to graph each option, only A would pass the vertical line test since no coordinate has the same x value

b.my answer is b.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
