Question
Plot the points $(5, 0), (5, 1), (5, 8)$. Do they lie on a line? What is your observation?

Answer
i. Take a point $O$ on the graph paper and draw horizontal and vertical lines $O X$ and $O Y$ respectively.
ii. Then, let on the $x$-axis and $y$ axis $1$ cm represents $1$ unit.
iii. In order to plot point $(5,0)$, we start from the origin $O$ and move $5$ cm along $O X$. The point we arrive at is point $(5,0)$.
iv. To plot point $(5,1)$, we move $5$ cm along $O X$ and $1$ cm along $O Y$. The point we arrive at is point $(5,1)$.
v. To plot point $(5,8)$, we move $5$ cm along $O X$ and $8$ cm along $O Y$. The point we arrive at is point $(5,8)$.
vi. From the graph below, it can be seen that the points lie on a line parallel to $y$-axis. This is because they have the same $x$-coordinate. $x-$coordinate.
