Need help with perpendicular line

#

to find the slope of a perpendicular line, you need to find the opposite reciprocal of the initial slope

#

with points (-5, 0), (0, 1), the slope should be 1/5. Not -1/5 because you're subtracting by a negative number which is equal to a positive:
0 - (-5) = 0 + 5
now to make it an opposite reciprocal, just flip the fraction and flip the sign
1/5 becomes -5/1

#

it doesn't seem like the question is asking you for a perpendicular line through a specific point so as long as the slope is -5, it will be a perpendicular line

#

i hope this helps
