Question

In figure, $ LM$ is a line parallel to the $ y-$axis at a distance of $ 3$ units. What is the difference between the abscissa of the points $ L$ and $ M$?

Answer 1

Compute the required difference:

The cartesian coordinates are of the form $(x,y)$. The ordered pairs in the two-dimensional plane are referred to as the abscissa and ordinate.

Abscissa: The first number in the ordered pair is called the abscissa. In other words, the value of $x$ in the ordered pair is called the abscissa. It is the distance of any point on the plane from the $y-$axis.

Since all the points on the line have the same abscissa $=3$.

The difference in abscissa of$L$ and $M=0$.

Hence, the required difference is $0$.
