Final answer:
The y-intercept of the equation y = -9 + 2 is -7, as it's the value of 'y' when 'x' is zero.
Step-by-step explanation:
The question is asking about the y-intercept of the equation y = -9 + 2. To find the y-intercept, we are looking for the value of 'y' when 'x' is zero. Since there are no 'x' terms in the given equation, we can determine the y-intercept by simplifying the right-hand side of the equation, which results in y = -9 + 2 = -7. Therefore, the y-intercept is -7.
