Jawaban:

$y = - 3x + 10 : = = = > m1 = - 3 \ tegak : lurus \ m2 = - frac{ 1}{m1} \ m2 = - frac{1}{ - 3 } \ m2 = frac{1}{3} \ melalui(4,-2) \ y - y1 = m2(x - x1) \ y - ( - 2) = frac{1}{3} (x - 4) \ - - - - - - - - - - times 3 \ 3y + 6 = 1(x - 4) \ 3y + 6 = x - 4 \ 3y - x + 6 + 4 = 0 \ 3y - x + 10 = 0 x-3y-10=0$
