We know,

The sign of coordinates in quadrants are as follow

\begin{gathered}\boxed{\begin{array}{c|c} \bf Quadrant & \bf sign \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf  {1}^{st}  & \sf (+, +) \\ \\ \sf  {2}^{nd}  & \sf ( - , +) \\ \\ \sf  {3}^{rd}  & \sf ( - ,  - ) \\ \\ \sf  {4}^{th}  & \sf (+,  - )\end{array}} \\ \end{gathered}

Remark :-

If the coordinates is of the form, (a, 0), it lies on x - axis and if it is of the form (0, a), it lies on y - axis.

Now,

According to statement,

\begin{gathered}\boxed{\begin{array}{c|c} \bf coordinate & \bf Quadrant \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf (3, - 4) & \sf  {4}^{th}  \\ \\ \sf (-5,7) & \sf  {2}^{nd}  \\ \\ \sf (2,0) & \sf lies \: on \: x \: axis \\ \\ \sf (3,5) & \sf  {1}^{st} \\ \\ \sf (4,-3) & \sf  {4}^{th} \\ \\ \sf (-7,2) & \sf  {2}^{nd} \\ \\ \sf (-8,0) & \sf lies \: on \: x \: axis\\ \\ \sf (-2,-10) & \sf  {3}^{rd} \\ \\ \sf (-9,50) & \sf  {2}^{nd} \end{array}} \\ \end{gathered}
