    Correct option: second one - > Rx + Py = PR

    Step-by-step explanation:

    we can model the equation of a line with the following equation:

    y = ax + b

    where a is the slope and b is the y intercept.

    From the y-intercept (0, R), we have that:

    R = a*0 + b

    b = R

    From the x-intercept (P, 0), we have that:

    0 = aP + b

    aP = - R

    a = - R/P

    So we have that:

    y = (-R/P) x + R

    Multiplying both sides by P, we have:

    Py = - Rx + PR

    Rx + Py = PR

    Correct option: second one
