Question

PLEASE HELP ASAP!!!!

A scatter plot is shown below: if you need an image of it look at the bottom

A graph shows numbers from 0 to 10 on the x axis at increments of 1 and the numbers 0 to 15 on the y axis at increments of 1. The ordered pairs 0, 14 and 1, 11 and 2, 9 and 3, 10 and 4, 7 and 5, 7 and 6, 5 and 7, 5 and 8, 3 and 9, 1 and 10, 0 are shown on the graph.

Which two ordered pairs can be joined to best draw the line of best fit for this scatter plot?

(4, 15) and (10, 7)
(1, 6) and (6, 0)
(0, 13) and (10, 11)
(0, 13) and (10, 0)

Answer 1

Last option

(0,13)

• The point will lie at top

(10,0)

• The point will lie at bottom

So

both will contain most no of plots so Option D is correct

Answer 2

Answer: Choice D. (0, 13) and (10, 0)

Reason:

If you were to draw a line through the points mentioned in choice A, the line wouldn't be close to the points since (4,15) isn't close to the points. The same goes for (10,7). So we can rule out choice A. Choices B and C are similar stories.

Choice D on the other hand has its line fairly close to all of the points.
