Question

Persamaan garis melalui titik (-2,5) dan sejajar garis x-3y+2=0 adalah...

gimana caranya ?

Answer 1

X-3y+2 = 0 (X & Y DIPISAH)
x = 3y - 2 
M = x/y = 1/3
m1 = m2

y-y1 = m(x-x1)
y-5= 1/3(x+2)
3y - 15 = x + 2
3y - x -17 = 0

Answer 2

M=1/3
y-y1=m(x-x1)
y - 5 = 1/3 (x - (-2))
y - 5 = 1/3x + 2/3
y - 1/3x - 17/3 = 0
