Graphing linear functions using a single point and slope

Graphing linear functions using a single point and slope

If we are given a single point and the slope of a straight line, we will be able to graph it. By the same token, we can determine the slope and intercepts if we are given from its graph.

  • 1.
    Graph the following line that passes through the given point and the slope
    a)
    (3,2); (-3, 2) ; m =23 {2 \over 3}

    b)
    (4,2); (4, -2); m = -35 {3 \over 5}

    c)
    (1,2); (1, 2); m = undefined

    d)
    (2,5); (2, 5); m = 0

    e)
    x int = 2; m = -1

    f)
    y int = -3; m = 32 {3 \over 2}
