Question

Without plotting the points indicate the quadrant in which they will lie, if (i) ordinate is $5$ and abscissa is $-3$ (ii) abscissa is $-5$ and ordinate is $-3$(iii) abscissa is $-5$ and ordinate is $3$ (iv) ordinate is $5$ and abscissa is $3$

Answer 1

Find the quadrant in which the points lie.

The sign of the quadrants are as shown below in the graph:

abscissa ${\displaystyle \equiv x}$-axis (horizontal) coordinate

ordinate ${\displaystyle \equiv y}$-axis (vertical) coordinate

So,

• The point whose ordinate is $5$ and abscissa is $-3$ will lie in second quadrant.
• The point whose abscissa is $-5$ and ordinate is $-3$will lie in third quadrant.
• The point whose abscissa is $-5$ and ordinate is $3$ will lie in second quadrant.
• The point whose ordinate is $5$ and abscissa is $3$ will lie in first quadrant.

Thus,

The point whose ordinate is $5$ and abscissa is $-3$ will lie in second quadrant.

The point whose abscissa is $-5$ and ordinate is $-3$will lie in third quadrant.

The point whose abscissa is $-5$ and ordinate is $3$ will lie in second quadrant.

The point whose ordinate is $5$ and abscissa is $3$ will lie in first quadrant.
