Find the intercepts and then use them to graph the equation.

3x + y = 6

To find the x-intercept, let y = 0 and solve for x:

3x + 0 = 6
3x = 6
x = 6/3
x = 2
The x-intercept is (2, 0).

To find the y-intercept, let x = 0 and solve for y:
3(0) + y = 6
y = 6
The y-intercept is (0, 6).

Now we can plot the intercepts on a graph and draw a line passing through them:
