Answer:
A: (-1,0)
B: (1,1)
C: (5,3)
(0,½)
(7,5) doesn't lie on the line 
Step-by-step explanation:
Slope: (3-1)/(5-1) = ½
y = ½x + c
0 = ½(-1) + c
c = ½
y = ½x + ½
(0,½) is on the line 
y = ½x + ½
Check for (7,5)
5 = 7/2 + 1/2
5 = 4 is a false statement 
 
        
                    
             
        
        
        
Answer:
Discontinuity at (-4,-2), zero at (-2,0).
Step-by-step explanation:
We are given that a function 

We have to find the discontinuity and zero of the given function.
Discontinuity: It is that point where the function is not defined.
It makes the function infinite.


When x=-4 then 
 It is indeterminate form
 It is indeterminate form 
Function is not defined 
After cancel out x+4 in numerator and denominator  then we get 

Substitute x=-4

Therefore, the point of discontinuity is (-4,-2).
Zero: The zero of the function is that number when substitute it in the given function then the function becomes zero.
When substitute x=-2
Then , 
The function is zero at (-2,0).
Hence, option C is true.
