    Exclamation Slopes of triangles???

    How would you find the slopes in an equation like this:

    The points L(4,0), M(10,0), and N(7,5) form Triangle LMN. What is the sum of the slopes of the three sides?

    Use the formula slope = \frac{y_2-y_1}{x_2-x_1} on each of the 3 sides in turn then add them together.

    hai..first thing theat you should do is to get the slopes of the lines that forms the triangle,then simlpy add them..:use the formula slope=y-y1/x-x2

    if you had questions,just reply...
