Question

A circle representing a pool is graphed with a center at the origin. Grant enters the pool at point A and swims over to a friend who is located at point B. Which equation represents Grant’s path? y = 2 – 4x y = 4 – y = 6 – y = 8 – 2x

Answer 1

you didn't attach figure. plz provide a complete question for getting answer quickly.
well, I attached required figure.


see figure, Grant enters the pool at point A (8, 0) and swims over to a friend who is located at point B( -4, 6).
we have to find equation of line joining points A and B.

first of all, find slope of line .
e.g., m = (6 - 0)/(-4 - 8) = 6/-12 = -1/2

now use formula , $(y-y_1)=m(x-x_1)$ to find equation of line.

(y - 0) = -1/2(x - 8)
y = -1/2x + 4
y = 4 - x/2
