Answer:
x = 1/20 y^2
Step-by-step explanation:
This is a rightward opening (sideways ) parabola
Directrix = x = -5
Distance formula form point x,y to directrix and focus are equal:
(x - -5)^2 = (x-5)^2 + y^2
x^2 + 10x + 25 = x^2 - 10x + 25 + y^2
20x = y^2
x = 1/20 y^2
You will get the incorrect answer because lining up the digits when adding or subtracting is important but it isn’t needed for multiplying.
Both rays and lines continue forever, therefore, a lime segment is the only choice that works.
