Plot the points (x, y) given in the following table on the plane, choosing suitable units of distance on the axes.

Solution:

Draw x-axis and y-axis as the co-ordinate axes and mark their point of intersection O as the origin (0, 0).

In order to plot the points given in the table provided above,

• Let us mark the first point as A (-2, 8)
  • Move 2 units on the negative x-axis and then 8 units on positive y-axis.
• Let us mark the second point as B (-1, 7)
  • Move 1 unit on the negative x-axis and then 7 units on the positive y-axis.
• Let us mark the third point as C (0, -1.25),
  • Move 1.25 units below the x-axis on the negative y-axis.
• Let us mark the fourth point as D (1, 3)
  • Move 1 unit on the positive x-axis and then 3 units on the positive y-axis.
• Let us mark the fifth point as E (3, -1)
  • Move 3 units on the positive x-axis and then move 1 unit on the negative x-axis.
