Question

The slope of a line is undefined. What is the slope of the line that is perpendicular to it?

Answer 1

mysterious?

Answer 2

0

Answer 3

undfined slope means vertical; perpendicular then means horizontal. horizontal lines have slope equal to zero

Answer 4

slope is the measure of the rate of increase/decrease of a line; horizontal lines neither increase nor decrease, thus slope=0

Answer 5

to find the slope of any line you could use "rise over run" the rise in a horizontal line is 0 so whatever the run may be (1, 2, 3, ect) if you put 0/2 it will be 0
