So if you're adding two negatives you move left, positive you move right, and when you have to determine a negative, and a positive you just have to see which one is the farthest from zero which the farthest one's sign is either positive, or negative. Positive to move right, and negative to move left.
        
             
        
        
        
Answer:

Pick a point and count how many steps up and how many steps to the right you need to make to get to the next point. That's how you find slope.
 
        
             
        
        
        
Answer:
Let two consecutive multiples of 3 be x and (x+3)
A/q,
x * (x+3) = 648
➡ x² + 3x = 648 
➡ x² + 3x -648 = 0
➡ x² + 27x - 24x -648 = 0
➡ x ( x + 27 ) -24 ( x +27)
➡ ( x - 24) ( x + 27)
➡ x = 24 and x = -27
so, we take x = 24.
Required multiples of 3 
➡ x = 24
➡ x +3 = 24+3 = 27.
 
        
                    
             
        
        
        
Answer:
132 kilometers
Step-by-step explanation:
Given: Pamela drove her car 99 kilometers and used 9 liters of fuel.
To find: Number of kilometers Pamela drove in 12 liters of fuel.
Solution: 
It is given that Pamela drove her car 99 kilometers and used 9 liters of fuel. Also the relationship between kilometers and fuel is proportional. 
So, let us assume that she can travel x kilometers in 12 liters of fuel.
By proportionality we have, 
 
 




Hence, she can travel 132 kilometers in 12 liters of petrol.
