#### Answer

Refer to the graph below.

#### Work Step by Step

To graph the given linear equation, look for three points that belong to the line.
To find three points on the line, assign a value to one variable and then solve for the value of the other variable.
When x = 0:
$x+y=6
\\0+y=6
\\y=6$
The point is $(0, 6)$.
When y = 0:
$x+y=6
\\x+0=6
\\x=6$
The point is $(6, 0)$.
When y = 3:
$x+y=6
\\x+3=6
\\x=6-3
\\x=3$
The point is $(3, 3)$.
Plot the three points and connect them using a straight line.
