Answer:
Really dude? 
Ok
In form ax + by = c
The slope is equal to (-a/b) 
And in this equation b is - 3 and a is 2 so 
Slope is equal to 2/3
 
        
                    
             
        
        
        
So, the rate per 7 minutes is 7:196
To find the unit rate (how many spins per minute) we need to divide the 196 by 7.
196/7 = 28
The unit rate is 1:28
At this rate, the unicycle makes 420 revolutions per 15 minutes. We find this by 28 * 15 = 420.
