tentukan PGL melalui titik (-2,5) dan sejajar garis x-3y= -2

Dik
(-2, 5) = (x1, y1)
x - 3y = -2
m = - a/b
m = - 1 / -3
m = 1/3 --------> karena ( // ) maka m1 = m2

Pers. Garisnya
y - y1 = m (x - x1)
y - 5 = 1/3 ( x - (-2)
y - 5 = 1/3 ( x + 2)
y - 5 = 1/3 x + 2/3 ------------> di kalikan 3
3y - 15 = x + 2
x - 3y + 15 + 2 = 0
x - 3y + 17 = 0 
atau
x - 3y = -17

semoga membantu 6_^
