2.) Tentukkan persamaan garis yg melalui (7,2) dan sejajar dengan garis 2x-5y = 10

m = - a/b
m= -2/-5
= 2/5

y-y1 = m (x-x1)
y-2 = 2/5 (x-7)
y-2 = 2/5x - 14/5
y = 2/5x - 14/5 + 2
(semua dikali 5)
5y = 2x -14 + 10
5y = 2x - 4
5y - 2x = -4

*dicek lagi ya takutnya kurang teliti

2x-5y= 10
5y= 2x-10
y= 2/5x-10
Gradien= 2/5

y-y1= m (x-x1)
y-2= 2/5 (x-7)
2(y-2)= 5 (x-7)
2y-4= 5x-35
2y-4-5x+35= 0
5x+2y+31= 0

Maaf kalo salah:)
