Question

How do you graph the line $x=4$ ?

Answer 1

Hint: In this question we have been asked to draw the graph of the given line $x=4$ . By observing the given line equation we can say that it has a constant “x” value for varying “y” values. Hence the given line will be parallel to the y-axis and passing through the point 4 on the x-axis.

Complete step by step solution:
Now considering from the question we have been asked to draw the graph of the given line $x=4$ .
By observing the given line equation we can say that it has a constant “x” value for varying “y” values. Hence the given line will be parallel to the y-axis and passing through the point 4 on the x-axis.
Hence, the given line will pass through (4,0) point.
The required graph of the given line equation will appear similar to the below shown graph:

Therefore we can conclude that the required graph of the given line equation is located above.

Note: During the process of answering questions of this type we should be sure with our concepts that we are going to apply and carefully plot the required graph. This is a very simple and easy question and can be answered in a short span of time. Very few mistakes are possible in questions of this type. Similarly a line equation in which the “y” value is constant will be parallel to the x-axis. For example the line having equation y=a will pass through (0,a) and lie parallel to x-axis.
