Answer:
Slope= 30
Speed = 30 miles per hour
Step-by-step explanation:
Given two points the slope will be change in y over change in x 
OR (y-y1)/(x-x1)
(120-60)/(2-1) = 60/2 = 30miles/hr
 
        
             
        
        
        
Answer: y = -2x + 7  
Step-by-step explanation:
Slope intercept form is the same as solving for y in the equation . 
So solve for y and it will be in slope intercept form. 
12 - y = 2x + 5   Subtract 12 from both sides 
-12             -12 
 -y = 2x  -7      Now divide both sides by -1 
y = -2x + 7

Answer:
5.50x>85 
if you divide 85 by 5.50 you get 15.4545455
