bantuin kaka please..
Penjelasan dengan langkah-langkah:
no.2 (0,3)(1,3)
gradien(m) = y2-y1 / x2- X1
= 3-3 / 1-0
= 0 / 1
= 0
no.3 (2,4)(2,1)
gradien(m) = y2-y1 / x2- X1
= 1-4 / 2-2
= -3 / 0 (gradien tidak terdefinisi)
no. 4
2x - py + 11 = 0 (2,-5)
2(2) - p(-5) + 11 = 0
4 + 5p + 11 = 0
5p + 15 = 0
5p = -15
p = -15/5
p = -3
no.5
(6,8)(-2,4)
y-y1 / y2-y1 = x-x1 / x2-x1
y-8 / 4-8 = x-6 / -2-6
y-8 / -4 = x-6 / -8
-8(y-8) = -4(x-6)
-8y + 64 = -4x + 24
4x - 8y + 40 = 0
x - 2y + 10 = 0
