Question

The line $x-7=0$ is:

• A. parallel to y-axis
• B. parallel to x-axis
• C. passing through the origin
• D. none of these

Answer 1

The correct option is A

parallel to y-axis

Step 1: Given data

$$\begin{gathered} x-7=0 \\ \Rightarrow x=7 \end{gathered}$$

Step 2: Plotting the abscissa on the graph

Scale :

$1cm=2$ units on x-axis

$1cm=2$ units on y-axis

Step 3: Inferring the graph

From the above graph, we understand that the line is parallel to the y - axis as the coordinate of x is fixed.

Hence, the correct answer is option A.
