Question

The abscissa of a point is 3 times the ordinate . If the sum of this ordinate and abscissa is 12, find the coordinates of the point.

Answer 1

Answer:

Coordinates of the point P (say) = (9,3)

Step-by-step explanation:

First of all, let's understand what abscissa and ordinate is.

→Abscissa : An abscissa refers to the x

coordinate of a point.

→Ordinate : An ordinate refers to the y coordinate of a point.

Given that "Abscissa of a point is 3 times the Ordinate".

Let abscissa and ordinate of the point be x and y respectively.

So, according to the question, x = 3y

Also, x + y = 12

Or, 3y + y = 12

Or, 4y = 12

Or, y = 12/4

Or, y = 3.

So, x = 3y = 3(3) = 9 and y = 3

So, coordinates of the point P (say) = (9,3)
