cliffordtapp one year ago if points (1,4) and (4,2) line on line k. what is the slope of the line that perpendicular to k.

First you have to find the slop of the slop of k. You find this from: $\frac{ \Delta y }{ \Delta x }$ As slope (or gradient) is just how much y changes with respect to x. Therefore the slop is =(4-2)/(1-4) =2/-3 =-2/3 If a line is perpendicular to another the gradients of both lines multiply to -1 (you can look up the reason why if you want its pretty simple) -2/3 * (gradient of perpindicularline) = -1 gradient of perpindicualr line = 3/2

wow is said slop twice :P i mean slope

And i just mean slope of k, not slope of slope of k. My grammar failed hard
