    Okay but I'm like lowkey positive the answer is - 1.14

    y = - 0.7x + 2.36

    x = 5

    y = (-0.7 x 5) + 2.36

    y = - 3.50 + 2.36

    y = - 1.14

    Answer with explanation:

    The Approximate line of best fit is given by the equation:

    y = - 0.7 x + 2.36

    We have to find, value of ordinate that is y, when, abscissa is 5.

    Putting, x=5, in the above equation, to get the value of y

    y = - 0.7 * 5 + 2.36

    = - 3.5 + 2.36

    = - 1.14

    →None of the option.

    if the equation has been like this

    y = - 0.7 x + 0.36

    y = - 0.7 * 5 + 0.36

    = - 3.5 + 0.36

    = - 3.14

    Option A: - 3.14
