    Answer: 0.74

    Step-by-step explanation:

    Slope is calculated as change in ydivided by change in x

    = y2 – y1/x2 – x1

    Step 1: Locate the coordinate points

    From the question,

    y2 = 66, y1= 15

    x2 =90, x1 =21

    Step 2:Then slot in the values into the formula

    Slope (m) = 66-15/90-21

    m = 51/69

    m = 0.739

    m is approximately 0.74

    Answer:

    17/23

    Step-by-step explanation:

    To find the slope of a line given 2 points, we use the formula

    m = (y2-y1)/ (x2-x1)

        = (66-15)/(90-21)

        = 51/69

    Divide the top and bottom by 3 to simplify the fraction

       = 17/23
