Answer:
x = -2, y = -2
Step-by-step explanation:
Your goal is to try and cancel out a variable. I want to get rid of y so i subtracted the first equation from the second one.
After that I solve for x and got x=-2.
I used x=-2 and plugged it back into either of the equation to solve for y.
 
        
             
        
        
        
Answer:
15 units per unit
Step-by-step explanation:
From the graph we can easily tell that y increases from 0 to 15 as x increases from 2 to 3.  
Thus, the average rate of change of f(x) on the interval [2, 3] is:
     1         15 - 0       15 units
--------- * ----------- = -------------- = 15 units (rise) per unit (run). 
  3 - 2          1                 1
