Find the slope of any line perpendicular to the line through points(0,5) and (-3,-4).
THis is what i did.
using points :(0,5)
so the slope of the perpendicular line is (-1)/(3)
When finding the slope, you got lucky. After (-4-5)/(-3-0) it is not 9/3, but -9/-3, which does equal 3. You got the slope right, but make sure you write it correctly.
The entire rest of the problem is correct.
so the perpendicular would be what i said of (-1)/(3).
and is it the same as : (3)/(-1).
The new slope is -1/3. But that isn't the same as 3/-1, that would be -3, which is different than -1/3
