    I only get one (2, 11)

    to find the points which are solutions, substitute the x-coordinate into the equation and if the value obtained equals the y-coordinate of the point then it is a solution

    (7, 16) : y = (3 × 7 ) + 5 = 21 + 5 = 26 ≠ 16

    ( – 2, 1): y = (3 × – 2) + 5 = – 6 + 5 = – 1 ≠ 1

    (2, 11) : y = (2 × 3) + 5 = 6 + 5 = 11

    ( – 7,16 ): y = (3 × – 7) + 5 = – 21 + 5 = – 16 ≠ 16

    the only point from the given list that is a solution is (2 , 11)
