Question 962613
Recall the distance formula for two points:
{{{L=sqrt((x_2-x_1)^2+(y_2-y_1)^2)}}}
Thus we plug in our given values:
{{{10=sqrt((9-3)^2+(y_2-(-2))^2)}}}
{{{10=sqrt(6^2+(y_2+2)^2)}}}
{{{10=sqrt(36+y_2^2+4y_2+4)}}}
{{{100=36+y_2^2+4y_2+4}}}
{{{y_2^2+4y_2-60=0}}}
{{{(y_2+10)(y_2-6)=0}}}
The solutions are (9,-10) and (9,6).
