    Choice C and D are the answer.

    Step-by-step explanation:

    We have given an expression.

    y = - 5x+2

    We have to choose the ordered pair (x, y) which satisfies the given equation.

    A. (5,49)

    49 = - 5 (5) + 2

    49 = - 25+2

    49 = - 23 (not true)

    B. (-3, 28)

    28 = - 5 (-3) + 2

    28 = 15+2

    28 = 17 (not true)

    C. (-6, 32)

    32 = - 5 (-6) + 2

    32 = 30+2

    32 = 32 true

    D. (4, - 18)

    -18 = - 5 (4) + 2

    -18 = - 20+2

    -18 = - 18 true

    Hence, (4, - 18) and (-6, 32) are the solutions of y = - 5x+2.

    Answer: (-6, 32) and (4,-18)

    Step-by-step explanation:

    Here the given expression is,

    y = - 5x + 2

    If a order pair satisfies the equation it is called its solution.

    For, (5, 49),

    49 = - 5 * 5 + 2 (False)

    For, (-3, 28),

    28 = - 5 * 3 + 2 (False)

    For (-6, 32)

    32 = - 5 * - 6 + 2 (true)

    For, (4, - 18)

    -18 = - 5 * 4 + 2 (True)

    Hence, only the order pairs (-6,32) and (4,-18) are satisfying the given equation,

    ⇒ (-6,32) and (4,-18) are the solution of the given equation.
