Find a formula that expresses the fact that P(x, y) is a distance 2 away from the origin.
A) $x + y ^ { 2 } = 2$
B) $$x ^ { 2 } + y ^ { 2 } = 2$$
C) $$x + y = 2$$
D) $\sqrt { x + y } = 4$
E) $\sqrt { x ^ { 2 } + y ^ { 2 } } = 2$

Quizplus · Accepted Answer

The distance from the origin to the point (x, y) is given by the formula $\sqrt{x^2 + y^2}$. Setting this equal to 2 gives $\sqrt{x^2 + y^2} = 2$.
