Jawaban:

1. Permisalan :

K = (-5,1)

L = (5, -5)

y - y1 = x - x1

y2 - y1 = x2 - x1

y - 1 = x - (-5)

-5 - 1 = 5 - (-5)

y - 1 = x + 5

-6 = 10

10(y-1) = -6(x+5)

10y - 10 = -6x - 30 > hasil dari perkalian silang

6x + 10y - 10 + 16 = 0

8x + 6y - 6 = 0 > masih bisa dibagi 2

8x + 6y - 3 = 0

2. (-2, 3)

Persamaan : 3x + 6 = 0

G¹ = -a

b

= -3

6

M1 x M2 = -1

M2 = -1/m1

M2 = -3/1

M2 = 3

y - y1 = m2(x-x1)

y - 3 = 3(x - (-2))

y - 3 = 3(x + 2)

y - 3 = 3x + 6

y = 3x + 6 - 3

y = 3x + 3
