3y = -2x-6
y = -2/3x -6/3
jadi gradiennya -2/3
m1 = m2 (sejajar)
m1 = -2/3
sehingga didapatkan :
y-y1 = m(x-x1)
y- (-2) = -2/3(x-5)
y+2 = (-2x+10)/3
3(y+2) = -2x +10
3y + 6 = -2x +10
3y = -2x +10-6
3y = -2x +4
3y + 2x - 4 = 0
jadi jawabannya A..
titik (-2,5)
dik:
a = 2
b = 3
x1 = -2
y1 = 5
karena sejajar, rumusnya:
ax + by = ax1 + by1
2x + 3y = (2)(-2) + (3)(5)
2x + 3y = -4 + 15
2x + 3y = 11
2x + 3y - 11 = 0 atau
3y + 2x - 11 = 0
jadi jawabanya c
fyi, kalo yg di soal diketahui tegak lurus. rumusnya : bx + ay = bx1 + ay1
maaf kalo ada kesalahan:)
