Question

Which of the following equations could be a line perpendicular to the x-axis?x = 8x = yy = –2y = –xI DON'T NEED AN EXPLANATION JUST THE ANSWER QUICK

Answer 1

Solution:

Concept:

The equation of the line perpendicular to the x-axis is` x=k`.
It is given that x=k has intercept -2 on the x-axis. This means that the line x=k passes through `(-2,0).

Step 1:

The graph of

$x=8$

is given below as

The graph of

$x=y$

is given below as

The graph of

$=-2$

Is given below as

The graph of

$y=-x$

Is given below as

Hence,

The final answer is OPTION A
