    Finding Coordinates of a Slope

    A lines passes through the point (1,-3). State the coordinates of one other point on the line so that the slope of the lines is:

    a. 4
    b. undefined
    c. (3/4)

    Please help. What's the formula to solve this? Thanks.

    Hi larry21,

    [a] slope = 4, points (1, -3) and (x, y)

    \frac{y_2-y_1}{x_2-x_1}=4

    \frac{y- ^-3}{x-1}=\frac{4}{1}

    y+3=4 \:\: and \:\: x-1=1

    y=1 \:\:and\:\:x=2

    (2, 1)

    Do you think you could follow these steps and complete
    the others?

    If the slope is "undefined" how would I solve it?

    Edit: Never mind, figured it out.
