x1 y1 x2 y2
2 4 3 -1

slope m = (y2-y1)/(x2-x1)
( -1 - 4 )/( 3 - 2 )
( -5 / 1 )
m= -5
The required line passes through both the points. So we select one point and plug it with the slope
Plug value of the slope and point ( 2 , 4 ) in
Y = m x + b
4.00 = -5 * 2 + b
4.00 = -10 + b
b= 4 + 10
b= 14
So the equation will be
Y = -5 x + 14
