Answer:
The function y = ⌊x⌋ is called the "greatest integer value" function.
it works as follows: the input is any number x, the output is the greatest  
integer smaller or equal to x.
For example:
⌊0.1⌋=0
⌊0.26⌋=0
⌊0.4678⌋=0
⌊0.8989⌋=0
⌊0.999⌋=0
⌊1⌋=0
⌊1.0001⌋=1
so, the value of ⌊x⌋, for the entire interval (0, 1] is 0.
Similarly,  
the value of ⌊x⌋, for the entire interval (1, 2] is 1.   and so on,  
thus the graph of  y = ⌊x⌋ is as shown in picture 1
the graph of   y = ⌊x⌋ – 2   is the graph of   y = ⌊x⌋   shifted 2 units down.
check picture 2.
 
        
             
        
        
        
Answer:
In addition, from the response shown, using a graphical calculator brings the following benefits:
 1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.
 2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.
 3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.

Answer:
-3/2. 
Step-by-step explanation:
To find the slope, we find the rise over run. 
In this case, the rise is 6 - 3 = 3. 
The run is 3 - 5 = -2. 
The slope is 3 / (-2) = -3/2.
Hope this helps!
