A K Upadhyay and S Upadhyay Solutions for Chapter: Coordinate Geometry, Exercise 3: TEST YOURSELF

The mirror image of $P(3,4)$ on $y$ axis is _____.

The distance of point $A(-4,2)$ from $x-$axis is _____ unit(s).

Plot $A(-3,7)$ and $B(4,4)$ on a graph. Join these points to the origin. What figure you will get?

Plot the points $A\left(0,5\right),B\left(\mathrm{8,0}\right),C(8,5)$ and join them. What figure do you obtain? Find the area of the figure.

Answer the following:

A point lies on $Y$-axis then which coordinate is zero?

What is the name of the point where the horizontal axis and vertical axis intersect in the cartesian plane?

If a point is at a distant $2 \mathrm{u}\mathrm{n}\mathrm{i}\mathrm{t}\mathrm{s}$ from $Y-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$ and $3 \mathrm{u}\mathrm{n}\mathrm{i}\mathrm{ts}$ from $X-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$. Write its coordinate.

Find the co-ordinates of the vertices of a rectangle placed in $III$ quadrant in the cartesian plane with length $\text{'}p\text{'}$ units on $X-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$ and breadth $\text{'}q\text{'}$ units on $Y-\mathrm{a}\mathrm{x}\mathrm{i}\mathrm{s}$.
