Value of constant #p# is #9.5#.

Explanation:

As the point #A(p,4)# lies on L1, whose equation is #4y+3=2x#. if we substitute values of #x# and #y# given by the coordinates of #A#, it should satisfy the equation.

i.e. #4xx4+3=2xxp#

or #16+3=2p#

or #2p=19#

i.e. #p=19/2=9.5#

Hence, value of constant #p# is #9.5#.
