Question

(-1,2) and perpenndicular to the line 2x-3y+5=0

Answer 1

ok - what do you know about the slopes of lines that are perpendicular to each other?

Answer 2

i dont know

Answer 3

I suggest you first read your notes on tat and then come back here.

Answer 4

*that

Answer 5

i dont have any notes

Answer 6

i came from another country so they did not teach anything about these

Answer 7

then why have they asked you this question?

Answer 8

but if u explain i know how to find

Answer 9

because i am entring to precal

Answer 10

use this site to learn about this: http://www.mathsisfun.com/perpendicular-parallel.html

Answer 11

oh come on perpendicular means 90 i know that

Answer 12

and they are parallel

Answer 13

i know this therom but i dont know how to find the point

Answer 14

I'm sorry but it is very difficult to judge how much you know just from chatting

Answer 15

itz ok

Answer 16

ok, this site would be better: http://www.purplemath.com/modules/slope2.htm

Answer 17

also this one: http://www.mathopenref.com/coordperpendicular.html

Answer 18

I need to go now, but I can describe what steps you will need to follow

Answer 19

ohk

Answer 20

1. find the slope of the line 2x-3y+5=0
2. use this to find the slope of a line that would be perpendicular to this
3. that will give you a value for m in the equation y = mx + b
4. use the point (-1,2) to calculate the value of b as we did in the previous question

Answer 21

do these steps make sense?

Answer 22

is slope 2/3

Answer 23

for step 1 - yes

Answer 24

I really need to go now - I'll check this when I log back in tomorrow.

good luck! :)

Answer 25

ohk thx

Answer 26

i got y=-3x/2+1/2

Answer 27

that is correct - well done! :)
