Without plotting the points indicate the quadrant in which they will lie, if abscissa is -5 and ordinate is -3

Solution:

Given, abscissa is -5

Also, ordinate is -3

We have to find the quadrant in which the given point lies without plotting the points.

The horizontal coordinate of a point in a plane cartesian coordinate system obtained by measuring parallel to the x-axis is called the abscissa of the point.

Given, abscissa is negative

The vertical coordinate of a point in a plane cartesian coordinate system obtained by measuring parallel to the y-axis is called the ordinate of the point.

Given, ordinate is negative

So, the point is (-5, -3)

Therefore, the point lies in the third quadrant as the x-coordinate and y-coordinate are negative.
