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

Solution:

Given, abscissa is 3

Also, ordinate is 5

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 positive

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 positive

So, the point is (3, 5)

Therefore, the point lies in the first quadrant as the x-coordinate and y-coordinate are positive.

Summary:

Signs of the coordinates of a point in the first quadrant are (+, +). If ordinate is 5 and abscissa is 3, the point (3, 5) lies in the first quadrant
