Question

Garis tegak lurus R(-6,8) dan 3x+2y=1

Answer 1

3x + 2y = 1 => m = -a/b = -3/2
karena tegak lurus : -3/2 . m = -1 => m = 2/3
pers garis yg melalui (-6,8) dan bergradien 2/3 adalah
y - y1 = m(x - x1)
=> y - 8 = 2/3 (x - (-6))
=> 3(y - 8) = 2(x + 6)
=> 3y - 24 = 2x + 12
=> 0 = 2x - 3y + 36
