Which of the equations below represents a line perpendicular to the x-axis? а. = — бу в. x= 6 c. x= у d. x= бу reset submit

Option B

Step-by-step explanation:

we know that

A line perpendicular to the x-axis is a line parallel to the y-axis

so

the equation of the line is of the form x=(+/-)a

The slope of the line is undefined

where

a is a real number

therefore

x=6 is a line perpendicular to the x-axis

B.

Step-by-step explanation:

The x-axis is the line of [horizontal line], therefore the ONLY live perpendicular to that would be , which is a vertical line, giving you a right angle in the centre.

I am joyous to assist you anytime.

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
