Answer:
b
Step-by-step explanation:
Point-slope form of equation is: 
Step-by-step explanation:
Given points are:
(2,-8) and (1,7)
First of all we have to calculate the slope of the line
so,

Point-slope form is given by:

Putting the value of slope

We can put any one of two given points in the equation to find the final form of point-slope form
So
Putting (1,7) in the equation

Hence, point-slope form of equation is: 
Reducing and simplifying
