8) - 2x - 5y + 10 = 0- 5y = 2x - 10
m = 2/-5
m = - 2/5 ( A )
9) 3x - 6y + 10 = 0
- 6y = - 3x - 10
m = - 3/-6
m = ½
jawabanya ( A )
10) ( y - y1 ) / ( y2 - y1 ) = ( x - x1 ) / ( x2 - x1 )
( y - 4) / ( 0 - 4 ) = ( x - 0) / ( 3 - 0)
( y - 4 ) / - 4 = x / 3
3 ( y - 4 ) = - 4x
3y - 12 = 4x
3y = 4x + 12
m = 4/3
c = 12 ( A )
