Question

Gradien kls 9. helpp:( ajarin caranya juga :)

Answer 1

3x - 2y + 6 = 0
-2y = -3x - 6
2y = 3x + 6
y = 3/2x + 3

y = mx + c
m = 3/2

y - b = m(x - a)
y - (-2) = 3/2(x - 6)
y + 2 = 3/2x - 9
-3/2x + y + 2 + 9 = 0
-3/2x + y + 11 = 0
3/2x - y - 11 = 0
kalikan 2
3x - 2y - 22 = 0

Answer 2

Ax + by + c = 0
 3x - 2y + 6 = 0

a = 3
b = -2
c = 6

m₁ = -a/b
     = -3/-2
     = 3/2

 m₁ = m₂
3/2 = m₂

                   y - y₁ = m(x - x₁)
                 y - (-2) = 3/2(x - 6)
                   y + 2 = 3/2x - 9
                 2y + 4 = 3x - 18
-3x + 2y + 4 + 18 = 0
      -3x + 2y + 22 = 0
         3x - 2y - 22 = 0

Jadi persamaan garisnya adalah 3x - 2y - 22 = 0 (C).
