What is the equation in point-slope form of a line that passes through the points (−4, −1) and (5, 7) ? y+1=87(x+4) y+4=98(x+1) y−1=89(x−4) y+1=89(x+4)

ANSWER

The equation in point-slope form is


EXPLANATION

The equation of a line in point slope form is given by,



where

is the slope and

is any given point on the line.

Let us now find the slope using the point,



We apply the slope formula,



This implies that,







The equation is now given by,



Or



The correct answer is D
