Using the given points, determine the slope. (8, 1) and (8, -4) slope = 0 slope = -5 slope is undefined user: a line has a rise of 3 and a run of 12. what is the slope? 4

(8,1)(8,-4)

notice how the x values are the samethis means that the line is a vertical line which has an undefined slope.

This helps :
VUX -- vertical line, undefined slope, represented by x = a number (if both values of x are the same)
HOY -- horizontal line, 0 slope, represented by y = a number (if both values of y are the same)

rise of 3 and a run of 12slope = rise / run...so ur slope is 3/12 which reduces to 1/4
