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

the slope i get is = 3

so the slope of any line perpendicular would be the reciprocal of 3 which is

-3/1

is that the correct answer.
or do i have to word it differenly like y = -3/1x + 5 if i'm using points (0,5)


slope is not three. Recheck

isn't slope y2-y1/x2-x1


so then that would be:

-4-5/-3-0=-9/-3=3
