F = 1.8C + 32
С = -10   ⇒   F = 1.8·(-10) + 32 = 14   ⇒   
(-10, 14)С = 0      ⇒   F = 1.8·(0) + 32 = 32      ⇒   
(0, 32)
С = 10    ⇒   F = 1.8·(10) + 32 = 50    ⇒   
(10, 50)С = 20    ⇒   F = 1.8·(20) + 32 = 68    ⇒   
(20, 68)
 
        
        
        
F(-1) = 12 - 5(-1)
f(-1) = 12 + 5
Solution: f(-1) = 17
        
                    
             
        
        
        
Answer:
M is 1.5
Step-by-step explanation:
Use M = 1/O
Replace 1 with a letter such as K
So you use M = K/O
Substitute values 
0.5 = K/6
To get K times 0.5 by 6
You get 3
So K=3
Use the equation from the start to find M
M=3/2
M IS 1.5
