Answer:
(0,-2), (5,0) and (10,2).
Step-by-step explanation:
Given equation is  .
.
Now we need to find 3 pairs of solutions in (x,y) form for the given equation.
As  is a linear equation so we are free to pick any number for x like x=0, 5, 10
 is a linear equation so we are free to pick any number for x like x=0, 5, 10
Plug x=0 into  , we get:
, we get:





Hence first solution is (0,-2)
We can repeat same process with x=5 and 10 to get the other solutions.
Hence final answer is (0,-2), (5,0) and (10,2).
 
        
                    
             
        
        
        
Add the two and you should get 2 and 7/16
        
             
        
        
        
This would be ( using the Pythagoras theorem) = sqrt (3^2 + 4^2)  = sqrt 25
= 5 units  (answer).
