Question

If you are finding the line perpendicular to x + 3y = 5, what is the slope of the perpendicular line?

Answer 1

do you know how to find slope ?

Answer 2

no

Answer 3

Answer 4

convert the equation into y=mx + b where m = slope

Answer 5

you have x + 3y = 5
3y = -x + 5
y = -1/3x + 5/3

now you have slope = - 1/3

Answer 6

now to be perpendicular you need the opposite reciprocal

Answer 7

opposite of negative is positive
reciprocal of 1/3 is 3/1 or 3

so the reciprocal is 3

Answer 8

sorry the perpendicular is 3

Answer 9

ok. I get it now. Thanks for your help.
