Here is your answer:
Independent Variable: Is a variable that is being tested..
Dependent Variable: Is a variable that's being measured.
So in this case.
The independent variable is water bottles in a case.
Dependent Variable: Is how many water bottles are in a case.
For this next part I'm not sure.
But as you look at the graph you see a pattern.
1×24=24
Etc...
So the equation will be: 1×24
The pattern is 24.
So....
1×24=24
2×24=48
5×24=120
10×24=240
20×24=480
Hope this Helps.
K=slope
b=y intercept
find slope
slope=(y2-y1)/(x2-x1)
(x,y)
(1,-2)
(-2,-8)
x1=1
y1=-2
x2=-2
y2=-8
slope=(-8-(-2))/(-2-1)=(-6)/(-3)=2/1=2
k=2
subsitute
y=2x+b
subsitute one point
(1,-2)
x=1,y=-2
-2=2(1)+b
-2=2+b
subtract 2
-4=b
y=2x-4
-4 2/5 / -5
-4 2/5 = -22/5
-5 = -5/1
-22/5 / -5/1
Flip -5/1 to multiply
-22/5 x 1/-5
Numerator x numerator / denominator x denominator
-22 x 1 = -22
5 x -5 = -25
-22/-25 = 22/25
The answer is 22/25.
No. A unit rate would be something like 6 2/3 miles per hour, which is the same speed as above.
