Question

Learn: Fitting a Linear Function to Data 1 of 31 of 3 Questions Question Use technology to find the line of best fit for the following data. (−17,8), (−14,7), (−11,6), (−12,4), (−10,1), (−7,3), (−3,2), (−3,0), (−2,−4), (0,−2), (2,−3), (6,−5), (4,−6) When the equation of the line is in the form y=mx+b, what is the value of b? Enter your answer as a decimal, like this: 42.25

Answer 1

One of the best ways to attack a problem like this one is to enter the point values in a graphing calculator as a linear regression under the STAT menu (ax + b). A graphing calculator will use the information from these points to generate the a and b values for you, which you could then use to graph the line of best fit.

y=ax+b

a=-0.6020457867

b=-2.256697516 <------- There is your value for b, which is the answer to the problem.

You can use these values for a and b to generate an equation in slope-intercept form, which you can then enter under Y= and view the graph.

y = -0.602x - 2.2567

Happy graphing!

Answer 2

I don't know which software or technology you are supposed to use but I simply put the points into an excel spreadsheet, graphed the data, and added the trend line and the equation for the trend line. I got the equation y = -0.602x-2.2567. Hopefully, this helps!
