    Answer:

    we get Rate of change = -3

    Step-by-step explanation:

    We need to calculate the rate of change for the following data:

    x     y

    -1     7

    2     -2

    7     -17

    10   -26

    The rate of change can be calculated using slope formula: [tex]Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}[/tex]

    From the table, we can take any 2 points

    Suppose we take (-1,7) and (2,-2)

    We have: [tex]x_1=-1, y_1=7,x_2=2, y_2=-2[/tex]

    Putting values in formula and finding rate of change

    [tex]Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:change=\frac{-2-7}{2-(-1)}\\Rate\:of\:change=\frac{-9}{2+1}\\Rate\:of\:change=\frac{-9}{3}\\Rate\:of\:change=-3[/tex]

    So, we get Rate of change = -3
