How do you find the equation of the line through the point (-4 , 5) and is perpendicular to the x axis?

Answer 1

Ethan Adkins

The answer is: #x=-4#.

Each line that is perpendicular to the x-axis can be expressed as follows:

#x=k#,

So, as the line has to pass from the point #(-4,5)#, the equation is:

#x=-4#.

Since the line is perpendicular to the x-axis, its slope is 0. Therefore, the equation of the line through the point (-4, 5) and perpendicular to the x-axis is ( y = 5 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
