Write an equation of the line that passes through a pair of points: (-4,-3), (-3,1)

The equation of the line is 4 x - y + 13 = 0.

Step-by-step explanation:

Here the given points are ( -4, -3) & ( -3, 1) -

Equation of a line whose points are given such that

( ) & ( )-

 y -   =    ( x - )

i.e.  y - (-3) =   ( x- (-4))

      y + 3 =  ( x + 4 )

      y + 3 =  ( x + 4 )

      y + 3=  4 ( x + 4)

      y + 3 = 4 x + 16

      4 x - y + 16 - 3 = 0

      4 x - y + 13 = 0

Hence the equation of the required line whose passes trough the points ( -4, -3) & ( - 3, 1)  is 4 x - y + 13=0 .
