Answer:
A
Step-by-step explanation:
y=x+1
=> put y=5 
5=x+1
x=5-1
x= 4
(4,5)
same put y=9
so, x= 8
(8,9)
 
        
             
        
        
        
Answer:
I am not sure but I think a or d is answer
I'm not quiet sure 
 
        
             
        
        
        
The midpoint formula is basically (averaging the x coordinates, averaging the y coordinates).
Point A: (3, 7)
Point B: (2, -1)
Midpoint x: (3 + 2) / 2 = 5 / 2
Mindpoint y: (7 - 1) / 2 = 3
Therefore, the midpoint of the segment is choice C (5/2, 3)
 
        
                    
             
        
        
        
Answer:
given sequence, -16; -9; -2: _
first term(a)=-16
common difference(d)=-9-(-16)=7
next term is 4
so
4th term=a+(n-1)d
=-16+(4-1)7=-16+21=5
