For making a scatter plot of the data set, which would be the best scale and interval for the axis

that represents the amount of fluoride?

0.5

2.5

water (l)

fluoride (mg)

1

0.4

0.5

0.4

0.8

0.6

2

1.6

1.5

0.8

1 to 3 with intervals of 1

1 to 25 with intervals of 0.5

0 to 2 with intervals of 0.2

oto 5 with intervals of 0.1

y=mx+b

step-by-step explanation:

m slope, b y-intercept

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

is there more to this question?

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
