Answer:
y = (-2/3)x + 1
Step-by-step explanation:
3y = -2x + 6
y = (-2/3)x + 2
y + 3 = (-2/3)(x - 6)
y + 3 = (-2/3)x + 4
y = (-2/3)x + 1

(One length side of the cube)³ - remember all sides of a cube are the same, just like how both sides of a square are the same. This is essentially the area of the square at the base, multiplied by the height of the cube.
Hence why we that that, for example 4³, is "4 cubed"
So we know that;
volume = (side length)³
Alternatively we could say that;
Side length = ∛volume
(we have just found the cube root of both sides here, remember we can do what we like to an equation, as long as we do the same to both sides!)
Because we cubed side length to get volume, side length must be the cubic root of the volume, the ∛.
We know that the volume is 1000 cubic feet, so;
Side length = ∛1000
∛1000 = 10
So one side length is 10 feet.

x is number of candy bars
y is cost
so the numbers are
100,165 and 600,196
first we want to make it into slope inercept form
y=mx+b m=slope, b=y inercept
slope= (y1-y2)/(x1-x2)=(165-196)/(100-600)=-31/-500=31/500
slope is 31/500
y=31/500x+b
subsitute
165=31/500(100)+b
165=31/5+b
subtract b from both sides
165-b=31/5
multiply both sides by 5
5(165-b)=31
325-5b=31
add 5 b to both sides
325=31+5b
subtaract 31 from both sides
294=5b
divide both sides by 5
48 and 4/5=b=48.8
y=31/500x+48.8
