    Answer: hi!

    (−3,2)

    and  

    (7,−1)

    The Slope is equal to the change in  

    y

    over the change in  

    x

    , or rise over run.

    m

    =

    change in y

    change in x

    The change in  

    x

    is equal to the difference in x-coordinates (also called run), and the change in  

    y

    is equal to the difference in y-coordinates (also called rise).

    m=y2−
    y1x2−x1

    Substitute in the values of :

    x and y

    into the equation to find the slope :

    m=− 1−(2)7−(−3)

    Simplify.

    Simplify the numerator.

    Multiply :

    −1 by 2.m= −1−27−(−3)  

    Subtract

    2

    from  

    −1.m= −37−(−3)

    Simplify the denominator.

    Multiply

    −1 by −3.m= −37+3

    Add  

    7

    and  

    3.m= −310

    Move the negative in front of the fraction.

    m= −310

    So once again you anwser is to :

    Use the slope formula to find the slope

    m.m
    = −310
