The graph below shows the line of best fit for data collected on the depth, in feet, and velocity, in feet per second, at ten points along the Columbia River. Which of the following is the equation of the line of best fit?

A.
y = -6.67x + 13
B.
y = -0.15x + 1.95
C.
y = -6.67x + 2.1
D.
y = -0.15x + 0.15

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
