Find the line of best fit for the set of data: x y

2 2.9

3.5 2

-1.4 4.8

4.2 1.5

0 4

-2.8 6

1.5 3.5

A: y = .613x + 4.142

B: y = -.613x - 4.142

C: y = -.613x + 4.142

D: y = .613x - 4.142

i did it myself and i got 4.2 (b) hope its right

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb
