    (1,3) means that x = 1 and y = 3. Let's make substitutions to see what happens with the inequality

    5*x + y < - 3

    5*1 + y < - 3 ... replace x with 1

    5*1 + 3 < - 3 ... replace y with 3

    5 + 3 < - 3

    8 < - 3

    This is false. The number 8 is NOT smaller than - 3.

    So (1,3) is NOT a solution

    Answer: Choice A) No
