Find the Equation of the Tangent Line to the Graph $x ^ { 2 }$

True/False

Find the equation of the tangent line to the graph of $x ^ { 2 }$ + $y ^ { 2 }$ = 1 at the point $\left( \frac { 1 } { 2 } , \frac { \sqrt { 3 } } { 2 } \right)$ .
Is $y = - \frac { 1 } { \sqrt { 3 } } x + \frac { 2 \sqrt { 3 } } { 3 }$ correct?
