Answer:
Step-by-step explanation:
Given the rectangular poster shown in the picture, you know that its dimensions (its width and its lenght) are:
In order to calculate the dimensions of the rectangular at 
times its current size, you need to multiply the original lenght by and multiply the original width by .
Knowing this, you get:
Direct variations look like this (y = 3x_
Not direct variations (or inverse variations) look like this (y= 1/3x.) They are often in fraction form.
So, in your problem the direct variations are:
y= 3x
x = -1
-0.5x = y
y= 2.2x +7
y= 4
The non-direct variations are:
y = 2/7x
