The slope of the graph x+y=5 is B -5
        
             
        
        
        
A) Slope:    (y2 - y1) / (x2 - x1)
You can use point  (-1, -6) and (0, -8)
Slope =    (-8 - -6) /(0 - -1) =   (-8+6)/(0+1) = -2/1  = -2.
Slope = -2.
b) Point (0, -8)  is the point such that  x = 0,  and y = -8, this point represents the vertical intercept  of the equation.  The point where the line cuts the y axis.

Answer:
Step-by-step explanation:
THE TRICK HERE IS TO DISTRIBUTE THE MINUS SIGN TO THE SECOND TERM.
(6X+5)-(X-3)=
6X+5-X+3   (REMEMBER A NEGATIVE TIMES A NEGATIVE EQUALS A POSITIVE) 
NOW COMBINE LIKE TERMS.
5X+8 
 
        
                    
             
        
        
        
Answer:
D). 8.
Step-by-step explanation:
Each quarter will come up heads or tails  - that is 2 possibilities.
So for  3 tosses the number of outcomes is 2*2*2 = 8.
