Answer
Refer to the image below for the graph.
Work Step by Step
(1) Solve for the x and y intercepts.
To find the x-intercept, set $y = 0$ and then solve for $x$:
$x+3y=6
\\x+3(0)= 6
\\x+0=6
\\x=6 $
This means that the x-intercept is at $(6, 0)$.
To find the y-intercept, set $x = 0$ and then solve for $y$:
$x+3y=6
\\0 +3y =6
\\3y=6
\\y=\frac{6}{3}
\\y=2$
This means that the y-intercept is at $(0, 2)$.
(2) Plot the intercepts and then connect them using a line.
