Visualizing Linear Functions (III)

Problem: Suppose that the variable y is a linear function of x with y = f (x) = mx + b. Given the following table for the function, move the points A, B, C, and D on the transformation figure to match the ordered pairs of data in the table. 

x
y = f (x)
3
2
0
-1

Based on this information, use the points E and F on the transformation figure (or the related Cartesian graph) to find an x so that f (x) = 0.
You can check your answer by clicking on the button to look at the Cartesian graph.

Here are two other tables of data. Assume that each is data from a linear function.
Use the transformation figure or the graph to estimate as well as possible the value of x so that f (x) = 0.
