What is an example of a vertical line test?
an example would be if you had line AB who's points are (5,3) and another at (1,5). Connecting diagonally. If you were to put a vertical line anywhere between the points. it only goes through one point. Making it a function.
What is the name of the vertical line?
A vertical line!
What is the slope of a line parallel to a vertical line?
A vertical line has an undefined slope. For the line to be parallel to a vertical line, the slopes would have to be the same. Therefore, the line parallel to a vertical line also has an undefined slope.
What is a line perpendicular to the vertical?
A horizontal line is a line perpendicular to the vertical.
Is a Verticle line positive or negative?
A vertical line is neither positive nor negative because the slope is undefined. An undefined slope creates a vertical line, hence no slope to calculate. An example of a vertical line would be x=2 or a "slope" of 2/0 (undef. slope). In addition, a vertical line is not even a function because it has repeating input(x) values.
