What is the equation of the line of best fit for the following data? Round the
slope and y-intercept of the line to three decimal places.
Х
y
4 17
6 12
8 9
11. 4
13. 3

This needs to be done quick you are studying different function tools and begin working with this function y=-160-9(x) use the equation to answer the question y=-160-9(x) what is the y value when x equals -13? y=-160-9(x)
