Find 2 coordinates on 2x - 3y = 4:
When x = 2 ⇒ 2(2) - 3y = 4 ⇒ y = 0 ⇒ coordinates (2, 0)
When x = 1 ⇒ 2(11) - 3y = 4 ⇒ y = 6 ⇒ coordinates (11, 6)
Plot 2x - 3y = 4 :

Find 2 coordinates on 3y - x = 4 :
When x = 2 ⇒ 3y - (2) = 4 ⇒ y = 2 ⇒ coordinate (2, 2)
When x = 11 ⇒ 3y - (11) = 4 ⇒ y = 5 ⇒ coordinate (11, 5)
Plot 3y - x = 4 :
