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?

A. -5
B. -2
C. 3
D. 12

answer is 67%

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
