The slope of this graph is - 4
Step-by-step explanation:
The slope of a line is  , where
 , where
 and and are two points on the line are two points on the line
- The slope of a horizontal line is zero
- The slope of a vertical line is undefined
∵ The graph is a line
∵ The line passes through points (1 , -2) and (0 , 2)
∴  = 1 and
 = 1 and  = 0
 = 0
∴  = -2 and
 = -2 and  = 2
 = 2
- Substitute these values in the rule below
∵ 
∴ 
∴ m = - 4
The slope of this graph is - 4

Answer:
16 units
Step-by-step explanation:
You would take the area of the door (which would be 8 times 3) and subtract the area of the poster (which is 4 times 2).
Next, you would set up your equation: 24-8 which is 16.
Hope this helps! :)
