Question

all vertical lines have a slope of ...

Answer 1

well, horizontal lines have horizontal slopes .... vertical lines have vertical slopes.

Answer 2

yeah but like horizontal lines have a slope of 0 what is the slope o vertical? 1

Answer 3

a vertical slope cannot be defined by a number .... in mathical terms: n/0 has no definition unless you attribute a meaning to it.

in this case: a vertical slope is defined by n/0 but the actual solution to the question is rather author specific.

Answer 4

we might as well define the slope of a line by the tangent of the angle it makes with the positive x axis.

the slope of a vertical line is therefore equal to: tan(90)

Answer 5

so its undefined

Answer 6

undefined is how some classes/authors define it yes

Answer 7

ok thanks
