Question

Which equation represents a line perpendicular to the x axis

x=-4
y=x+2
y=2
y=x

Answer 1

Answer:

x = -4

Step-by-step explanation:

with x = -4 , a perpendicular line at -4 on the x axis reveals that x is alway -4...all the way along the perpendicular line.  Y will be changing values as the perpendicular line goes up or down

Answer 2

X=-4

No matter what ‘y’ is ‘x’ will always be -4, which will show as a vertical line, perpendicular to the x axis.
