Question

Joseph compared the graphs of two functions. The first function wasf(x)=−2x+6. The second function fits the values in the table: x 2 5 8 11 y 2 -4 -10 -16 What is the distance between the y-intercepts of the two functions?

Answer 1

Answer: No difference

Explanation:

The function f(x)=-2x+6 will produce the very same points in the table.

x y y calculated

2 2 2

5 -4 -4

8 -10 -10

11 -16 -16

The points are all on the line y=-2x+6. They describe the same line, which will have the same intercept.
