tlong plisss bsok dikumpulinnn

III.2x-y=5
-a/b = -2/-1 = 2

IV.y=2x-3
y=mx-c = 2

3 dan 4
yg D

smoga mmbantu :D

pasangan garis sejajar , jika gradien =m= sama

(i)  x + 2y =10
2y = - x +10 →  m1 = -1/2

(ii) 3x - 6y =7
-6y = -3x + 7  → m2 = -3/-6  = 1/2

(iii)  2x -y = 5 
-y = - 2x + 5 → m3 = -2/-1= 2

(iv) y = 2x - 3→ m4= 2/1 = 2

pasangan yg sejajar = (iii) dan (iv) krn m = 2
