To find the y-intercept of the line y = 3x - 9, we substitute 0 in for x and solve for y.

Step 1: Substitute 0 in for x in the equation y = 3x - 9
y = 3(0) - 9

Step 2: Simplify the equation
y = 0 - 9

Step 3: Simplify further to find the y-intercept
y = -9

So, the y-intercept of the line y = 3x - 9 is -9.
