ANSWER

Therefore the correct answer is B




Step-by-step explanation

The equation in the point slope form of a straight line is given by the formula;


y-y_1=m(x-x_1), where
m is the slope and the point
(x_1,y_1) is any point on the line.


Since two points on the line are given, Lamont must find the slope using the points
(-8,5) and
(-5,7) as follows;


m=(7-5)/(-5--8) =(7-5)/(-5+8) =(2)/(3).


He can now choose one of the points as
(x_1,y_1).

If he uses
(-8,5), the he obtains,



y-5=(2)/(3)(x--8)

Which gives
y-5=(2)/(3)(x+8) as the equation of the line.


Therefore the correct answer is B
