Example Questions
Example Question #1 : Linear Functions
Which of the following is a horizontal line?
A horizontal line has infinitely many values for , but only one possible value for
. Thus, it is always of the form
, where
is a constant. Horizontal lines have a slope of
. The only equation of this form is
.
Example Question #1 : Linear Functions
Which of the following is a vertical line?
A vertical line is one in which the values can vary. Namely, there is only one possible value for
, and
can be any number. Thus, by this description, the only vertical line listed is
.
Example Question #2 : Linear Functions
Which of the following has a slope of 0?
A line with a slope of zero will be horizontal. A horizontal line has only one possible value for , and
can be any value.
Thus, the only given equation which fits this description is .
