Any equation with the form y=c is parallel to the y-axis, where c is a constant.
Any line with the equation [ x = any number ] is parallel to the y-axis.
5 units, x axis
A line that is parallel to the y-axis is a vertical line. The equation of a vertical line is of the form ( x = k ), where ( k ) is a constant. Since the line passes through the points ( (4, y) ) and ( (3, y) ), the line that is parallel to the y-axis and passes through these points would have the equation ( x = 4 ) or ( x = 3 ), depending on which point you choose.
x=0
Any equation with the form y=c is parallel to the y-axis, where c is a constant.
[ y = plus or minus any number ] is parallel to the x-axis.
x=4
That is impossible, because, if it is parallel to it, it can not be above it nor below it.
To determine the units of the y-intercept in a linear equation, you need to look at the units of the y-axis. The y-intercept represents the value of y when x is zero, so the units of the y-intercept will be the same as the units on the y-axis.
Any line with the equation [ x = any number ] is parallel to the y-axis.
y=-2.5 is parallel to the x axis. The equation of the x axis is y=0

In 2-dimensional co-ordinate geometry, a line parallel to the y axis has the equation x = c where c is a constant.
x=0
lines of lattitude extend up the y axis but are parallel to/on the x axis
