    Answer:

    y=-\frac{2}{7} x+7

    Step-by-step explanation:

    First Solve For The Slope Using The Two Given Points!

    M = Slope

    M = \frac{y2-y1}{x2-x1}

    M = \frac{5-9}{7--7}           Two negative signs together makes addition!

    M = \frac{-4}{14}               Move the negative sign (only if the fraction has a negative)

    M = -\frac{4}{14}            Simplify

    M = -\frac{2}{7}              Final Answer

    Then see how many units the graph goes up = y-intercept

    Answer: 7
