Question

Find the equation of the line perpendicular to x axis and having intercept -2 on x axis.

Answer 1

Answer:

Step-by-step explanation:

A line perpendicular to the y-axis is parallel

to the x-axis. Since the slope is defined as

(change in y)/(change in x), the slope is zero.

There is never any change in y no matter what

the change in x is.

The general equation for a straight line is:

 

y+=+mx+%2B+b where m is the slope

and b is the y-intercept.

I just said m=0 for the line perpendicular

to the y-axis, so

y+=+0%2Ax+%2B+b

y+=+b

The problem says the y-intercept is -5

y+=+-5 answer
