Question

Give an example of a linear quation whose graph is: 1) A horizontal line and 2) A vertical line.

Answer 1

On a horizontal line, the value of y does not change since the line does not rise or fall. So if y does not change, then y is equal to a constant. For example y = -8.

Answer 2

On a vertical line, the line never runs to the right or the left but it rises forever in both directions. So if x does not change, then x is a constant. For example x = -8.

Answer 3

Okay I gotcha thanks a lot.
