The Vertical Line Test for Functions:

If any vertical line intercepts a graph in more than one point, the graph does not define y as a function of x.

By the definition of a function, for each value of x we can have at most one value for y.

What is a best-fit line as a math definition?

Best-fit line is used in a graph with a whole bunch of dots. If the dots are grouped up and that they are all going in a direction if there is one then there should be a best-fit line which is only a line going down there path to point that it's not changing.


What can you say about a line if every point on the line has the same x coordinate?

Oh, dude, if every point on a line has the same x coordinate, that means the line is vertical! It's like the line is standing at attention, with all its points stacked on top of each other in a straight up and down fashion. So yeah, in math lingo, we call that a vertical line with an equation like x = a, where 'a' is the x coordinate all the points share. Cool, right?


What happens when the slope is 3 over 0?

When the slope is 3 over 0, it indicates a vertical line. In mathematical terms, a slope of 3 over 0 is considered undefined because division by zero is undefined in mathematics. This means that the line is vertical and does not have a defined slope in the traditional sense. The equation of a vertical line can be represented as x = a, where 'a' is the x-coordinate of any point on the line.
