What should larmont do to write a correct point slope equation for this line? <br> (-8,5) and (-5,7)
Ronch [10]

ANSWER

Therefore the correct answer is B




<u>EXPLANATION</u>

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=\frac{7-5}{-5--8} =\frac{7-5}{-5+8} =\frac{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=\frac{2}{3}(x--8)

Which gives y-5=\frac{2}{3}(x+8) as the equation of the line.


Therefore the correct answer is B
