Brittni0605Best ResponseYou've already chosen the best response.1
What do you know about the slopes of perpendicular lines?

i used a program called geogebra.
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
Programs are good, but its important to know how to do it by hand.

TahminaBest ResponseYou've already chosen the best response.0
I know i found it but I dont want to use it
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
Ok, do you want me to help you?

It is very simple yo use. They even provide help for you too solve these kind of probelms.

Yes I need your help Brittni0605

Ok, so what do you know about the slopes of perpendicular lines?
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
you have to multiply them by 1
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
Umm, sort of on the right track. Perpendicular lines have slopes that are negative reciprocals. Do you know what that means?
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
No can u be a little clear on that?
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
So you mean B mutiply 3 *1/3

TahminaBest ResponseYou've already chosen the best response.0
i got 3 because its the slope isnt it?

TahminaBest ResponseYou've already chosen the best response.0
Okay whats the slope then wait you need to find the slope first rite?
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
No, its not 3. Show me your work.
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
Your work is correct. But you said the slope is 3. Your work shows something different.
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
oh sorry its negative 3 thanks for showing that
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
No prob. SO, now that you know the slope of your line is 3, what is the slope of its perpendicular line?
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
wait what about the points (6,7)
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
No, remember if the slope of your line is 6, the slope of its perpendicular line is the negative reciprocal (1/6)
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
wiat whats the slope of the perspendicular then
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
Perpendicular slope is the negative reciprocal of the slope of your line
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
so the slope of my line is 3 that means my perpendicular slope is 3 *1/3 rite?
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
No, you're not multiplying anything.
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
so my perpendicular lines slope is 1/3 rite
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
so do i substitute with y=mx+b
 one year ago

TahminaBest ResponseYou've already chosen the best response.0
can u check my work???/
 one year ago

Brittni0605Best ResponseYou've already chosen the best response.1
Yes, ill check your work.
