Answer:

The relation is a function.
The domain and range are both all real numbers, or #(-oo, oo)#

Explanation:

First, this relation is a function. A function means that the input only has ONE output, or that each x-value can only have ONE y-value.

This equation #y = 7x - 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 #(-oo, oo)#
