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

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 ${-oo, oo}$

The range is all y values ${-oo, oo}$

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