# What is the domain and range of y = 6x + 3?

Sep 27, 2015

First, sketch a graph of the equation then determine the domain and range.

#### Explanation:

Here is a graph of the equation:

graph{6x+3 [-10.53, 9.47, -4.96, 5.04]}

As you can see, this is a straight line with slope 6 and y-intercept equal to 3.

The domain is all x values $\left\{- \infty , \infty\right\}$

The range is all y values $\left\{- \infty , \infty\right\}$
