Final answer:
The question appears to be misstated, referencing a linear function (y = a + bx) instead of a product (f(x) = a * b). The information provided pertains to linear relationships, discussing y-intercepts and slopes, which cannot be directly applied to finding a product of two variables. Without correct information or a specific graph, it is impossible to determine the values of a and b.
Step-by-step explanation:
The student is asking about determining the values of a and b in a function of the form f(x) = a * b. However, the information provided seems to reference a different form — a linear relation of the form y = a + bx. In this context, a represents the y-intercept, and b is the slope of the line.
The provided information and figures suggest a focus on linear relationships, where we look at the y-intercept and the slope. For example, based on the information about a line graph with a y-intercept of 9 and a slope of 3, we would conclude the equation for this line is y = 9 + 3x, with a as 9 and b as 3. However, the student seems to be asking about a product of two variables, not a linear sum.
Without a specific graph or a clear statement of the function form, we can’t determine a and b uniquely. We would need additional details or a correctly presented graph to find the correct values for a and b.
