Question

use the set of points displayed on the graph to place a “line of best fit”. Then determine the slope of this line. use the set of points displayed on the graph to place a “line of best fit”. Then determine the slope of this line. @Mathematics

Answer 1

best fit usually has to do with linear regression

Answer 2

theres an excel technique for this, but I cant recall it

Answer 4

Just draw a line that best represents all the points (so one that goes through the middle) calculate the slope using rise/run method, and y intercept to go into y=mx+b form

Answer 5

best fit doesnt amount to guessing at a line :)

Answer 6

Sure it does, especially when the points are given on a piece of graph paper like that :) at least back when I was in high school that is the way I was taught.

Answer 7

with that many points, id go with excel if you can

Answer 8

granted, a fitted line is fine, but the "best" fit hmmmm

Answer 9

Yes, there is a function on excel to do this. Plot your points, create a graph, then right click the graph and select to display the equation of the best fit line.
