We have been given that

Now, we need to find an ordered pair that must be on the graph of 

On substituting x=0 in the above equation, we get
 
Therefore, the required ordered pair is given by (0,-1)
 
        
             
        
        
        
Answer:
168 seconds
I edited the answer.
Step-by-step explanation:
To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.
28 x 6 = 168, 24 x 7 = 168
The LCM of 28 and 24 is 168.
So it takes 168 seconds for both lights to flash at the same time.
 
        
                    
             
        
        
        
Answer:
We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units
