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
Vertical lines only intersect the x-axis. This means that the equation of a vertical line is x=n. The variable n is the coordinate where on the x-axis the line goes.
Because you have only given the point at which a line crosses the "x" axis. Since x = 4, we can draw it only vertically through (4,0).
"The" vertical line is wrong; there are lots of vertical lines on a coordinate plane. In the usual x-y coordinate system, such a line has an equation of the form:x = a (for some constant "a"); for example: x = 3

WHY THE LINE X=4 IS A VERTICAL LINE.
The equation of a vertical line passing through the point (-4,0) is x = -4. Since all points on a vertical line have the same x-coordinate, the equation is simply x = -4.
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.
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 line x = -4 is vertical, so a line that is perpendicular to it is horizontal, so its slope is 0.
