Plot a line graph for the variables p and q where p is two times q i.e, the equation is p = 2q. Then find.
- the value of p when q = 3
- the value of q when p = 8
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 |
- When q = 3, the value of p is 6.
- When p = 8, the value of q is 4.
