tolong dibantu ya?yang bisa tolong dijawab?

Bab Persamaan Garis
Matematika SMP Kelas VIII

A(2, -6) dan B (-3, 3)

(y - ya)/(yb - ya) = (x - xa)/(xb - xa)
(y - (-6)) / (3 - (-6)) = (x - 2) / (-3 - 2)
(y + 6) / (3 + 6) = (x - 2) / (-5)
-5 . (y + 6) = 9 (x - 2)
-5y - 30 = 9x - 18
-5y = 9x - 18 + 30
y = -9x/5 -12/5

gradien = -9/5

tegak lurus
m1 x m2 = -1
-9/5 x m2 = -1
m2 = -1 x (-5/9)
m2 = 5/9

maaf y kalo salah
goodluck
