Question
What is the equation for the line of best fit that matches the data shown in the table and in the graph?
x y
-7 9
-3 6
-1 3
2 1
6 -1
A. y = 0.79x - 3.12
B. y = -0.79x + 3.12
C. y = 3.12x - 0.79
D. y = -3.12x + 0.79
i can't show the graph here but it's basically a plot of the given points on a coordinate grid. i don't have the appropriate calculator to do this problem, so i can't get my answer.
