Question

Choose the equation of the line conaining the point (-5, 10) and with undefined slope.


How can I do this? And what does it mean undefined slope? That may sound stupid but what would be the solution if it was a "defined slope" ? If such thing exists.

Answer 1

vertical lines have undefined slope.
equation of vertical line is of the form x=c
where c is the x co-ordinate.

Answer 2

do you know what a slope is ?

Answer 3

I cant say I do :F

Answer 4

slope means how bent the line is,
you can calculate slope (m) given 2 points using
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)

its basically ratio of change in y co-ordinates to change in x co-ordinate.
