Answer:
The graph is attached.

The relation is function.
Step-by-step explanation:
Find the x-intercept. Substitute
into the equation and solve for "x". Then, this is:

The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
In this case "b" is:

Therefore, since the line passes through the points (
and
, you can graph it. (Observe the graph attached)
Since it is a line, then <em>the relation is a function</em>, and the Domain and the Range of Linear Functions are:
