y = 1/2 x -3
Explanation: the y-intercept is where it crosses the y axis so the y-intercept is -3

All proportions have <u>this</u> <u>form</u>:
, Where
is equal to
.
If
, it's <u>not</u> a proportion.

Here we have two pairs of numbers:
40,10 and 32,8.
Written As a <u>proportion</u>, they <em>look like</em> :
![\sf{\dfrac{40}{10}=\dfrac{32}{8}}](https://tex.z-dn.net/?f=%5Csf%7B%5Cdfrac%7B40%7D%7B10%7D%3D%5Cdfrac%7B32%7D%7B8%7D%7D)
Hope this made sense to you :)

Answer:
I think it should be ![24x^{2}](https://tex.z-dn.net/?f=24x%5E%7B2%7D)
Step-by-step explanation:
When the question said area of the cube, I think it was supposed to be surface area, which would
where a is the length of one edge. Given that the length of one edge is 2x, we would plug in 2x to the equation to get
which would become
.
I can't really graph this for you but here's some points.
(X, Y): (-4, 0), (-3, 3), (-2, 0), (-1, -3), (0,0)
Here's the end behavior:
x⇒∞, y⇒∞
x⇒-∞, y⇒-∞
The decimal equivalent of 3/7 rounded to the nearest hundreds is 0.428
