    y = 5x + 3

    Step-by-step explanation:

    Parallel lines have the same slope.

    Your function is

    y = 5x - 2

    slope = 5

    The line must have slope = 5.

    (a) y = 5x + 3

    slope = 5, ∴ Parallel.

    (b) y = 1 / (5x) + 3.

    Not a straight line. ∴ Not parallel.

    (c) y = - 5x + 3

    slope = - 5 ∴ Not parallel.

    (d) y = - 1 / (5x) + 3

    Not a straight line. ∴ Not parallel.

    The Figure below shows the graph of y = 5x - 2 (black) and that of the parallel line y = 5x + 3 (green).

    I think it should be y=5x+3
