I’m not sure what you’re options are but an equation in Y=mx+b form for this would be y= -3/2x + 5 
M is always the slope 
B is always the y intercept
        
             
        
        
        
Answer:
The experimental probability of the coin landing tails-side up is <u>60</u><u>%</u><u>.</u>
Step-by-step explanation:
The probability of it landing heads up is 4/10. You can use 4/10 to find how many times it landed on tails.
10/10 - 4/10= 6/10 now convert 6/10 into a percentage, 60/100=<u>60%</u>
 
        
                    
             
        
        
        
multiply 3.5 x 3 = 10.5
 add -5 +-10 = -15
 so you have 10.5 x 10^15
 then you need to move the decimal point 1 place to the left to get 1.05
 since you move the decimal point 1 place to the left you add 1 to the -15 to get -14
 so answer = 1.05 x 10^-14
 
        
             
        
        
        
E. II or IV only because it will have different signs if point Q was in either of those quadrants
