A)

2/5

B)

3/4

    Answer:

    B. 3/4

    Step-by-step explanation:

    😉 i dont know jk i do know

    Each point should satisfy the equation of the line it belongs to.

    This means that:

    for the equation of the first line (y=x+b), the point (p,r) satisfies this equation, thus: r = p + b …….> equation I

    for the equation of the second line (y=2x+b), the point (2p,5r) satisfies this equation, thus: 5r = 4p + b ………> equation II

    Subtract equation I from equation II to eliminate the constant b:

    5r-r = 4p+b-p-b

    4r = 3p

    Thus, r/p = 3/4
