Find the equation of the line that passes through point a (1,7) and b (-3, -1)

The equation of the line is 2 x - y + 5 = 0.

Step-by-step explanation:

Here the given points are A( 1, 7) & B( -3, - 1) -

Equation of a line whose points are given such that

( ) & ( )-

 y -  =   ( x -  )

i.e.  y - 7=  ( x- 1)

      y - 7 =   ( x -1)

      y - 7 =  2 ( x - 1)

      y - 7  =   2  x - 2

      2 x - y + 5 = 0

Hence the equation of the required line whose passes trough the points ( 1, 7) & ( -3, -1)  is 2 x - y  + 5 = 0.
