Answer 1

Verified answer

( y - y1 ) / ( y2 - y1 ) = ( x - x1 ) / ( x2 - x1 )
( y - 1 ) / ( - 3 - 1 ) = ( x + 2 ) / ( - 4 + 2 )
( y - 1 ) / - 4 = ( x + 2 ) / - 2
- 2 ( y - 1 ) = - 4 ( x + 2)
- 2y + 2 = - 4x - 8
- 2y + 4x = - 8 - 2
- 2y + 4x = - 10
2y - 4x = 10

Answer 2

Pers y-y1=m (x-x1) dan m=y-y1/x-x1
2x-y+5=0
