A vertical line on a graph has infinite slope and no y-intercept. Its equation is [ x = a number ]. The number is the line's x-intercept.
No because a line can be a vertical line so say you have the equation x=5. Then a vertical line would pass through the x intercept 5 and be vertical thus not having a y intercept. All horizontal lines have a y intercept
In terms of the slope intercept form of the line, it is undefined. A vertical line is not a function since a single value of x is mapped onto infinitely many y values.
slope: y=mx+b the y-intercept is vertical
explain why a function has at most one y-intercept
X = 3 A vertical line not having a Y intercept.
No. It would not be a function if it crosses any vertical line more than once.
It is the y-intercept.

A vertical line on a graph has an infinite slope, and no y-intercept.
A vertical line does not have a slope - negative or positive. It is not defined. A vertical line has no y intercept and, if its equation is x = c (for some number c), then the x-intercept is (c, 0).
In terms of the slope intercept form of the line, it is undefined. A vertical line is not a function since a single value of x is mapped onto infinitely many y values.
No. Use the vertical line test along the Y axis and if the line is crossed more than once, you know that it isn't a function.
If x is horizontal distance in your graph, and y is vertical distance, the vertical intercept is what y is when x=0. For example, if x is the time since you started a business, and y is how much your business is worth, the vertical intercept is how much money you started off with.
