Question

Perpendicular to the graph of y= 1/3x+7

Answer 1

do you know how to find the perpendicular slope?

Answer 2

I know it is the reciprocal and the opposite of 1/3x right?

Answer 3

yep so what is the slope?

Answer 4

-3/1x or -3x

Answer 5

yep now if you sub that into y=mx +b for m you have a equation for the perpendicular line :)

Answer 6

I am taking online college and as my homework I put y=-3/1x+7 and my teacher said its wrong, something about the y-intercept??

Answer 7

i would not know why thats wrong then is there more information to the question?

Answer 8

hold on ill get it

Answer 9

The question is:Wright the slope-intercept equation of the line whose graph is described.
Perpendicular to the graph of y=1/3x+7 with the y-intercept of (0,5)

maybe I have to sub 5 where the 7 is????

Answer 10

yep :) because 7 is the y-intercept and the question tells us to have a 5 y-intercept :)

Answer 11

Okay Thanks. I feel dumb now lol.

Answer 12

its all good i misread all the time is a common mistake it gets the best people sometimes :)

Answer 13

thanks again!!

Answer 14

no problem :)
