उत्तर

Given, equation is p = 2q

If p = 2, then q = `p/2 = 2/2` = 1

If p = 4, then q = `p/2 = 4/2` = 2

If p = 6, then q = `p/2 = 6/2` = 3

If p = 8, then q = `p/2 = 8/2` = 4

Hence, table for the graph

p 2 4 6 8
q 1 2 3 4

  1. When q = 3, the value of p is 6.
  2. When p = 8, the value of q is 4.
