Question

The line L1 has equation 4y+3=2x. The point A (p,4) lies on L1. How do you find the value of the constant p?

Answer 1

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`.
