Question

Nomor 3 kk gue tau jawabn na tapi pengen cara make persamaan..

Answer 1

Cari gradien pers 4x-3y+6 = 0

m = - A/B = -4/-3 = 4/3

sejajar m1 = m
                    = 4/3

pers garisnya yang melalui (-3,-3) --> a = -3, b = -3

y - b = m1 (x -a)
y + 3 = 4/3 (x+3)
-------------------------x 3
3y + 9 = 4x+ 12
        0 = 4x - 3y + 3

atau 4x - 3y + 3  = 0 

Answer 2

Koef. x × x₁ = 4 × -3 = -12
Koef. y × y₁ = -3 × -3 = 9

4x - 3y - ( -12 + 9 ) = 0
4x - 3y - (-3) = 0
4x - 3y + 3 = 0
