The graph shows a linear relation between variable y and x. Consider two quantities p and q defined by the equations.
`p=y/x`
`q=(y-b)/x`

As x changes from zero to a, which quantity will increase and decrease

Answer

`[M^(-1)L^(-3)T^(3)A^(2)]`

Explanation

Electrical conductivity
`sigma=J/ErArr [sigma]=[(I//A)/(F//q)]=[(I//A)/(F//it)]=[(I^(2)t)/(FA)]`
`=[(A^(2)T)/((MLT^(-2))(L^(2)))]=[M^(-1)L^(-3)T^(3)A^(2)]`
