How do we find the x-intercept of 3x + 2y = 6? Set y = 0 and solve the resulting equation for x:
3x + 0 = 6, or x = 2. The x-intercept is then (0, 2).
y-intercept? Do the same thing, except set x = 0 and solve for y:
3(0) + 2y = 6, or y = 3. The y-int is then (0,3).
You will see problems of this type over and over in algebra, so it'd be best that you learn how to do them now.
