  • Given,
  • i) x + 2y = 3
  • put x = 0
  • 0 +2y = 3
  • ∴ y = 3/2
  • put y = 0
  • x + 2(0) = 3
  • ∴ x = 3
  • Now, we have points (0, 3/2) and (3,0)
  • (0, 1.5)  and (3,0)
  • ii) 2x - 3y = 5
  • put x = 0
  • 2(0) - 3y = 5
  • ∴ y = -5/3
  • put y = 0
  • 2x - 3(0) = 5
  • ∴ x = 5/2
  • Now, we have points (0, -5/3) and (5/2,0)
  • (0, -1.667)  and (2.5, 0)
  • iii) x + y = 4, x - y = 1
  • solving above equations, we get,
  • x = 5/2
  • 5/2 + y = 4
  • y = 3/2
  • 5/2 - y = 1
  • y =  3/2
  • (5/2 , 3/2)
  • now,
  • put x = 0 in x + y =4
  • y = 4
  • put y = 0 in x + y =4
  • x = 4
  • (0,4) and (4,0)
  • now,
  • put x = 0 in x - y = 1
  • y = -1
  • put y = 0 in x - y = 1
  • x = 1
  • (0, -1) and (1,0)
  • For (iii) we get a total of 5 points
  • (5/2 , 3/2), (0, 4), (4, 0), (0, -1), (1, 0)
  • (2.5 , 1.5), (0, 4), (4, 0), (0, -1), (1, 0)
