bisa tolong jawab dari 24-30 harus jawaban betul ya

24a) 3x - 6y + 11 = 0
- 6y = - 3x - 11
m = - 3/-6
m = ½

b) 4x + 3y = 8
3y = - 4x + 8
m = - 4/3

c) 3x = - 2y + 7
- 2y = 3x - 7
m = 3/-2
m = - 3/2

d) y = - 3x - 7
m = - 3

25) m = ( y2 - y1 ) / ( x2 - x1 )
m = ( 0 - 3 ) / ( - 1 - 3 )
m = - 3 / - 4
m = ¾
subtitusi ke salah satu titik
y - y1 = m ( x - x1 )
y - 3 = ¾ ( x - 2)
y = ¾ x - 3/2 + 3 ( dikali 4 )
4y = 3x - 6 + 12
4y = 3x + 6

26) m = ( y2 - y1 ) / ( x2 - x1 )
m = ( 2 - 1 ) / ( - 1 - 1 )
m = 1 / - 2
m = - ½
subtitusi ke salah satu titik
y - y1 = m ( x - x1 )
y - 1 = - ½ ( x - 1 )
y = - ½ x + ½ + 1 ( dikali 2)
2y = - x + 1 + 2
2y + x = 3

27) y - y1 = m ( x - x1 )
y + 4 = 3/2 ( x - 3)
y = 3/2 x - 9/2 - 4 ( dikali 2)
2y = 3x - 9 - 8
2y - 3x = - 17

28) y - y1 = m ( x - x1 )
y + 3 = 8 ( x - 1 )
y = 8x - 8 - 3
y - 8x = - 11
