    Slope/midpoint of the line

    Can someone help me find the midpoint of the line segment joining (4,8) and (-2,-6)? Also, find the slope of the line joining the points A (-3,2) and B (0,4) Thanks!

    The midpt. of a line with coo'rds (x_1, y_1) and (x_2, y_2) is

    (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})

    Slope of a line with aforementioned coo'rds is

    \frac{y_2-y_1}{x_2-x_1}

    Jay1,

    Go back and study your formulas. These questions are easy if you know them. You need to learn these.

    MIDPOINT FORMULA:

    M=\left(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\right)

    SLOPE FORMULA:

    m=\frac{y_2-y_1}{x_2-x_1}

    Yes, jay1, you have asked a series of questions that depend only on basic definitions and formulas. Do you not have your text book with you to look up the formulas? I hope you are not using this forum as a way of avoiding looking things up yourself!
