Final answer:
The y-intercept of the equation y=-4x+9 is (0, 9).
Step-by-step explanation:
The y-intercept of the equation y=-4x+9 is the point where the graph of the equation intersects the y-axis. In the given equation, the constant term is 9, which represents the value of y when x is 0. Therefore, the y-intercept is at the point (0, 9).
