Question

write the equation of the line in point slope form:

through (-1, 4) and (-1, 7)

Answer 1

use the slope formula y2-y1/x2-x2

Answer 2

I worked it out and the slope is undefined... so how do I put it into point slope form? (y-y1=m(x-x1)

Answer 3

yes it means the line is vertical so all you write is x=-1 no matter what y values would be x will always equal -1

Answer 4

but what do you substitute for m in the equation of point slope form because m is undefined!!! I need this answer!!!

Answer 5

help me plz I will give a medal!

Answer 6

nothing the equatio is x=-1 which is a vertical line

Answer 7

so the equation in point slope form would be:

y+1= (x+1)

right???

Answer 8

no forget about the slope. because the slope is undefined the equation will only be
X=-1. if you graph the equation you only get a vertical line

Answer 9

i know that i get a vertical line but i still don't get how to put it in that form... never mind

Answer 10

i gave you a medal

Answer 11

it wont go to the for of mx+b this is special straight line.

Answer 12

The line is x = -1.

Answer 13

i meant the form y2- y1= m (x-x1)

Answer 14

do see this drawing that how the line looks like

Answer 15

i know what it looks like, i need the point slope form of the equation! i get that in slope intercept it would be x=-1, but i just don't get how to do it for point slope form! can you write the equation in point slope form for me?

Answer 16

It can't be written in the point slope form.

Answer 17

so... I leave the answer blank?

Answer 18

undifined slope

Answer 19

Explain and draw the line and show that the equation is x = -1. Slope is undefined....etc. etc.! You have a lot to write than leave blank.

Answer 20

my assignment was to write the equation of the line in point slope form, slope intercept form, and standard form... pretend this is the assignment, and write those answers for me as the question should be answered

Answer 21

no drawing needed, just equation

Answer 22

Standard form will be x=-1

Answer 23

what about point slope and slope intercept! im kinda getting annoyed... no offense...

Answer 24

hhhhhhhhheeeeeeeeeeeeellllllllllllllllllllllllllllpppppppppppppp!!!

Answer 25

How many ways should I say it is undefined in those forms?

Answer 26

what does your question says

Answer 27

he/she cant understand

Answer 28

keeping in mind that the 2 points given were (-1, 4) and (-1, 7) and the slope is undefined, how do i put rewrite that info into the equation:
y-y1= m (x- x1)
m is the slope, y1 is 7, and x1 is -1

Answer 29

We know. m is undefined. so the whole thing is undefined.

Answer 30

no no

Answer 31

so i should write as my answer: undefined

???

Answer 32

forget about rewriting the equation just go with X=-1 thats the answer it does not apply to this type of graph

Answer 33

yes m- undifined

Answer 34

okay i'll just ask my mom never mind gotta go bye

Answer 35

have fun
