@Sparklestaraa

Answer 5

so following the line of best fit when x=40 what does y=?

Answer 6

ya i pluged it in

Answer 7

Help please i need to know if i'm right

Answer 8

so what is the equation of the line?

Answer 9

(10, 20) (30, 60)

Answer 10

look at 30 on the graph where it meets up with 40 on the y axis

Answer 11

60 - 20 40
------- = --- = 2
30 - 10 20

Answer 12

so the equation for the line is y=x+10 right?

Answer 13

no i think its 80

Answer 14

The answer

Answer 15

im still not sure where you got that from

Answer 16

Then when i get 2

Answer 17

i plug it into the formula y - y1 = m ( x - x1)

Answer 18

Which would be y - 20 = 2 ( x - 10)

Answer 19

@NickR

Answer 20

but the slope is only 1

Answer 21

how

Answer 22

40 divide by 20 is 2
