Consider the graph provided below and assume that the values of x and y change together at a constant rate of change.
a. Determine the constant rate of change of y with respect to x .
b. Starting at point ( - 3.1, 8.18) , what is the change in the value of x (i.e. Δx ) from this point to x = 2 ?
c. What is the change in y (i.e. Δy )that corresponds with Δx found in part (b)?
d. Using Δy from part (c), what is the value of y when x = 2?
