Recall that the y-intercept is when the function passes the y-axis. This happens when x=0. Therefore, we can find our y-intercept by plugging x=0 into our function and solving for y.

6x + 9y = 18

6 (0) + 9y = 18

0 + 9y = 18

9y = 18

y = 2

Thus, our y-intercept is when x = 0 and y = 2, or (0,2).
