Text Solution

Steps:

To determine the quadrant or axis of the points \((–2, 4), (3, –1), (–1, 0), (1, 2)\) and \((–3, –5)\).

Plot the points \((–2, 4), (3, –1), (–1, 0), (1, 2)\) and \((–3, –5)\) on the graph, to get

From the figure above, we can conclude that the points

  • Point \((–2, 4)\) lie in \(2^\rm{nd}\) quadrant    
  • Point \((3, –1)\) lie in \(4^\rm{th}\) quadrant
  • Point \((–1, 0)\) lie on the negative \(x-\)axis.
  • Point \((1, 2)\) lie in \(1^\rm{st}\) quadrant.
  • Point \((–3, –5)\) lie in \(3^\rm{rd} \)quadrant.
