# Math Help - Finding Coordinates of a Slope

1. ## 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)

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?

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

Edit: Never mind, figured it out.
