Y=(-3) include parentheses 
Explanation: 
y=mx+b is the slope intercept form of a line where b and y is the intercept so, 
x-y=x+3: y= -3
        
             
        
        
        
Answer:
see below
Step-by-step explanation:
-33, -27, -21, -15,....
-33 +6 = -27  
-27+6 = -21 
-21+6 = -15
This is an arithmetic sequence
The common difference is +6
explicit formula
an=a1+(n-1)d  where n is the term number and d is the common difference
an = -33 + ( n-1) 6
an = -33 +6n -6
an = -39+6n
recursive formula
an+1 = an +6
10th term 
n =10
a10  = -39+6*10
       = -39+60
       =21
sum formula

The sum will diverge since we are adding infinite numbers

1 3/9 but if reduce to lowest term than 1 1/3
        
                    
             
        
        
        
Set up trig ratio using tangent. 
Tan theta = opp/adj
Tan theta = 500/800
Tan^-1 (500/800) = 32 degrees
