It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.
 
        
                    
             
        
        
        
Answer:
B
Step-by-step explanation:
To find the constant of proportionality between y and x, divide   for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
 for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
Using the method above, you should get:
Chart A = 2/5
Chart B = 1/5 (Correct Answer!)
Chart C = N/A
Hope this helps!
