Question

How do you graph $x = 8$ by plotting points?

Answer 1

In the given question, we have been asked to graph the line $x = 8$. Now, this line is going to be parallel to the y-axis. Hence, that means that its y-coordinate is going to be zero. The given value of the x-coordinate gives us the offset from the origin vertically, i.e., how far is the line from the origin when you count in the direction of the abscissa.

Complete step by step solution:
The given equation of the line is $x = 8$. This line is going to be parallel to the y-axis, which means that it is never going to touch the y-axis, i.e., the ordinate of this line is always going to be zero.
Now, we graph the line by taking eight points right (because the value of $x$ is positive) of the origin in the direction of the x-axis.

Note:
So, for solving questions of such type, we first write what has been given to us. Then we write down what we have to find. Then we write the formula which connects the two things. In this question, we only need to know one thing – when is the line going to be parallel to the x-axis and when to the y-axis. Then we just count the number of points in that orientation, plot it on the graph and we are going to get the answer.
