-Find the equation of a line passing through the origin so that the sine of the angle between the line in quadrant $I$ and the positive $x$-axis is $\frac { \sqrt { 2 } } { 2 }$.
A) $y = \frac { \sqrt { 3 } } { 3 } x$
B) $y = \sqrt { 3 } x$
C) $y = \frac { \sqrt { 2 } } { 2 } x$
D) $y = x$

Quizplus · Accepted Answer

The sine of the angle between the line and the positive x-axis being $\frac{\sqrt{2}}{2}$ corresponds to an angle of $45^\circ$, which means the line has a slope of $1$, leading to the equation $y = x$.
