# How do you find the domain and range and determine whether the relation is a function given :y=7x-6?

Dec 23, 2017

The domain and range are both all real numbers, or $\left(- \infty , \infty\right)$
This equation $y = 7 x - 6$ is a line on the graph. All non-vertical lines are functions.
Also, since it is a line, that means that the domain and range are both all real numbers, or $\left(- \infty , \infty\right)$
