The x-intercept would have the sample coordinate of (x, 0) -- where y = 0
The y-intercept would have the sample coordinate of (0, y) -- where x = 0
The x-intercept can be found by:
3x - 0 = 6
3x = 6
x = 2
x-intercept is (2, 0)
The y-intercept can be found by:
3(0) - y = 6
-y = 6
y = -6
y-intercept is (0, -6)
So just graph those two coordinates and then draw a straight line through them.
