A K Upadhyay and S Upadhyay Solutions for Chapter: Coordinate Geometry, Exercise 1: EXERCISE 3.1

In which quadrant, can a point have:

Without plotting the given point on a graph paper indicate the quadrant in which they lie, if ordinate $=-3,$ abscissa $=3$

Plot points $P(-\mathrm{3,4})$ and $Q\left(\mathrm{1,1}\right)$ on a graph paper. What is the distance of point $P$ and $Q$ from $x-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$? Find the vertical distance between $P$ and $Q$.

The point $(0,-3)$ lies on the $x-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$.

The point $(-2,-4)$ lies in the $III$ quadrant.

The mirror image of the point $(3,5)$ in the $X-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$ is $\mathrm{P}\text{'}(-3,5).$

The mirror image of the point $A(4,-2)$ in the $Y-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$ is $A\text{'}(4,2).$

The perpendicular distance of the point $P(-\mathrm{2,3})$ from $\mathrm{X}-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$ is $3 \mathrm{u}\mathrm{n}\mathrm{i}\mathrm{t}\mathrm{s}$
