Find the slope of any line perpendicular to the line through points (0,5) and(-3,-4).

I found the slope to be 3, but would the answer to the question be -1/3 ? what are your thoughts??

The slope of your given line is
(y2-y1)/(x2-x1) = (-4 -5)/(-3-0)
= -9/-3 = 3

The slope of any perpendicular line to your given line it must be -1/3, since the product of the two slopes must be -1.

what is one fools dream fools
