Question

MANAKAH DIANTARA GARIS GARIS BERIKUT YANG SALING TEGAK LURUS

1. y = 2x + 8
2. y = -2x
3. y = 2/5x - 3
4. x = 3y - 7
5. 3x = 5y + 6
6. 6y = x - 12
7. 2y - 4x = 0
8. 6x + 5y = 4
9. x + 3y - 3 = 0
10. 2x + 7y +15 = 0

Answer 1

1. m = 2
2. m = -2
3. m = 2/5
4. m = 1/3
5. m = 3/5
6. m = 1/6
7. m = 2
8. m = - 6/5
9. m = - 1/3
10.m = - 2/7

yang saling tegak lurus :
tidak ada
maaf kalau salah
