The y-intercept of a graph is the point where the graph intersects the y-axis, which occurs when \( x = 0 \). Based on your information, the possible responses for the y-intercept include coordinates. The correct answer would be the y-coordinate at \( x = 0 \).
Assuming the y-intercept corresponds to one of the choices you provided, if you have the specific graph image with the parabola, you would look for the point at which the parabola crosses the y-axis to determine the y-intercept.
From the options given, if we assume the graph shows that at \( x = 0 \), \( y = -50 \), then the y-intercept would be:
(0, -50)
However, verify this against the graph to ensure accuracy. If the graph shows a different value for the y-intercept at \( x = 0 \), that would be your answer.
