A line of best fit is f(x) ≈ −0.86x + 13.5 for the set of points in the table.



Using the equation for the line of best fit, what is a good approximation for the value of the function, f(x), when x = 18?

−5
−2
3
12

f(x) = -0.86x + 13.5
when x = 18, then
f(18) = -0.86(18) + 13.5 = -15.48 + 13.5 = -1.98

i.e. when x = 18, f(x) = -1.98
