[AI-generated answer — Bot GPT 3.5]

To find the y-intercept of the linear function 9x + 3y = 21, we need to set x = 0 and solve for y.

Plugging in x = 0 into the equation, we get:
9(0) + 3y = 21
0 + 3y = 21
3y = 21
y = 21/3
y = 7

Therefore, the y-intercept of the linear function 9x + 3y = 21 is 7.
