The lines are parallel to each other, or oppisit of each other any x=# will always be vertical and anything y=# will be horizontal.

WHY THE LINE X=4 IS A VERTICAL LINE.
When x = 4 is graphed in an xy plane, it is easy to see why a vertical line is formed. At every value of y, x = 4. Plot enough points like this on your graph and you will soon form a vertical line.
x=4
x = 4 is a straight line that is vertical when plotted on the xy graph, where y is the vertical axis and x is the horizontal axis. A vertical line has an infinite slope; the slope is infinity
If you have X=4, that is a vertical line. No matter what value y possesses, x is always four. X=4 when Y=0, X=4 when Y=1, X=4 when Y=-1, and so on.
A line with the equation:x = a constant valueis a vertical line. Examples of such a line are x = 3, x = 5, x = 10, x = -4.The slope of a vertical line is infinite.
A vertical line in the xy coordinate plane would represent the line of an equation such as x = 1 or x = -4.
No, it is horizontal.
X = 4 graphs to a vertical line because the x axis is horizontal, and if a line always has a constant x value of 4, it will not move horizontally, because to do that, the x value has to change.
That would be because all the graphed values of x are 4. So you can plug anything in for Y and it will still be on that vertical line.
The equation of the line x = 4 has no term for y in the equation. Therefore any value of y can be used and the x coordinate is still equal 4. So a straight vertical line, crossing the x axis at (4,0) is the only line which satisfies these conditions. You can plot some points: (4,0); (4,100); (4,-5265), etc. and then connect the dots to see that it is a straight vertical line.
The vertical line that passes through the point (0, 4) is the Y-axis. Its equation isX = 0
