Question

Given the data set (10, 45), (25, 70), (46, 105), which of the following equations best represents a line of best fit?

y = one thirdx + 40.5
y = five thirdsx + 28.33
y = four thirdsx − 40.5
y = three fifthsx − 28.33

Answer 1

45

Answer 2

a

Answer 3

Yes thank you. Wait how did you figure that out?

Answer 4

cat be a

Answer 5

cant be a

Answer 6

Then what is it?

Answer 7

its b

Answer 8

Ok how did you get that?

Answer 9

take any 2 points and find the equation of that line

Answer 10

I did that but I got lost on the 45 because I got a weird number when I did it.

Answer 11

ok i will walk you through it

Answer 12

Okay thank you.

Answer 13

lets take the first 2 points (10, 45), (25, 70), lets first find the slop with is( y2-y1/x2-x1)

Answer 14

let me know if you understand this

Answer 15

.Okay. I get it but I thought you were supposed to divide?

Answer 16

yes (70-45) divided by (25-10)=25/15 which can be reduced to 5/3

Answer 17

Oh okay thank you so much.

Answer 18

Can you help me with another question? Please
