3x + 3y - 7 = 0
Penjelasan dengan langkah-langkah:
parabola y = 3x² - 3x - 4
y - x + 2 = 0
y = x - 2
m = 1
m2 = -1 : 1
= -1
mencari absis
y = 3x² - 3x - 4
y' = 6x - 3
y' = m
6x - 3 = -1
6x = -1 + 3
= -2
x = -2/6 = -1/3
mencari ordinat
= 3(-1/3)² - 3(-1/3) - 4
= 1/3 + 1 - 4
= 2 2/3
persamaan garisnya
y - 2 2/3 = -1(x - (-1/3))
y - 8/3 = -1(x + 1/3) kedua ruas x3
3y - 8 = -3(x + 1/3)
3y - 8 = -3x - 1
3y - 8 + 3x + 1 = 0
