Question

Which equation best describes the line of best fit for the given data?
y = 1/2x

y = -1/2x

y = 2x

y = –2x

Answer 1

Any ideas?

Answer 2

no clue haha

Answer 3

Do you know what "slope" means in math?

Answer 4

well yeah, it describes the steepness, incline, or grade of a line

Answer 5

Good, what would negative slope mean?

Answer 6

the negative correlation between the two variables of a function

Answer 7

True, but I meant visually on a graph :)

Answer 8

the best fit line would be the line that roughly bisects the points, there should be about the same number of points on each side of the line, so draw that in and what does the slope look closest to?

Answer 9

Are you still there?

Answer 10

Do you still care?

Answer 11

yes sorry im here

Answer 12

What do all the lines have in common?

Answer 13

negative x coordinate?

Answer 14

or just negative slope

Answer 15

Why would you say that?

Answer 16

Why would you say they all have "negative" slope?

Answer 17

You said slope "describes the steepness, incline, or grade of a line", right?
