Which equation is a point slope form equation for line ab ?

Option C

equation :  

Step-by-step explanation:

Point slope form Equation states that the equation of a straight line in the form ;   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   = (6 ,5)

First find the value of m:

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

or

Then, the equation of line:

Substitute the value of slope in above equation and the coordinates of we have,

Therefore, the equation for the point slope form is,
