Which function has the greatest constant of variation? A x 8 9 10 11 y 20 22.5 25 27.5 B x 1 2 3 4 y 3.2 6.4 9.6 12.8
Lina20 [59]

Answer : B x 1 2 3 4 y 3.2 6.4 9.6 12.8

WE analyze the first option A

x -- y -- Difference

8 -- 20

9 -- 22.5 -- 2.5

10 -- 25 -- 2.5

11 -- 27.5 -- 2.5

From the first function we can see there is a constant difference of 2.5.

We analyze the second option B

x -- y -- Difference

1 -- 3.2

2 -- 6.4 -- 3.2

3 -- 9.6 -- 3.2

48 -- 12.8 -- 3.2

From the second function we can see there is a constant difference of 3.2

3.2 is the greatest

So second function B has the greatest constant of variation.

IM STRUGGLING HELP <br> What is the equation of the line in the form y=Mx+b
Andrej [43]

y=3x+6

Step-by-step explanation:

point 1 (2;12)

point 2 (4;18)

m =  \frac{y2 - y1}{x2 - x1}

m =  \frac{18 - 12}{4 - 2}

m =  \frac{6}{2}

m=3

y=mx+b

sub in a point and gradient

12=3(2)+b

12=6+b

b=6

y=3x+6
