Answer:
Option C
equation :  
Step-by-step explanation:
<u>Point slope form Equation</u> states that the equation of a straight line in the form  ;   where m is the slope of the line.
;   where m is the slope of the line.
 We have to find the equation for line AB.
From the figure, we have 
The coordinate of  =  ( -2, -1) and
 =  ( -2, -1) and   = (6 ,5)
 = (6 ,5)
First find the value of m:

Now, substitute the points of A and B into slope m:   
 or
 or

Then, the equation of line: 
Substitute the value of slope in above equation and the coordinates of  we have,
 we have,
 
Therefore, the equation for the point slope form is,
