Question

Help, please !!!!

A scatter plot is shown on the coordinate plane.

scatter plot with points at 1 comma 9, 2 comma 7, 3 comma 5, 3 comma 9, 4 comma 3, 5 comma 7, 6 comma 5, and 9 comma 5

Which two points would a line of fit go through to best fit the data?

(1, 9) and (9, 5)
(1, 9) and (5, 7)
(2, 7) and (4, 3)
(2, 7) and (6, 5)

Answer 1

(2,7) and (6,5)

Explanation:

The line of best fit would be approximately:

y = -.4x + 8

(1,9)

9 = -.4(1) + 8

9 = 7.6

(9,5)

y = -.4x + 8

5 = -.4(9) + 8

5 = 4.4

(5,7)

y = -.4x + 8

7 = -.4(5) + 8

7 = 6

(2,7)

y = -.4x + 8

7 = -.4(2) + 8

7 = 7.2

(4,3)

y = -.4x + 8

3 = -.4(4) + 8

3 = 6.4

(6,5)

y = -.4x + 8

5 = -.4(6) + 8

5 = 5.6
