I need help with the following:
Find the slope of the line that goes through the given points. (-1,-2) and (-2,-1)
Select the correct choice below and if necessary, fill in the answer box.
a) the slope of the line is _____________
b)the slope is undefined.

Answer 1

you can use the point slope form

Answer 2

point slope formula
y-y1 = m(x-x1)

m = slope

Answer 3

I am thinking that the slope is undefined??

Answer 4

your can try it out

Answer 5

I am lost! :(

Answer 6

do you know how to plug in the values for y and x?

Answer 7

no

Answer 8

I should...I am just lost & seemed to have forgotten everything

Answer 9

this is how you use the point slope formula
y-y1 = m (x-x1)

(x , y) this corresponds to 1 the x1 and y 1
do not get them mixed up
(X, Y) this corresponds to the x and y

i am not capitalizing purposely only to have you get used to seeing this

Answer 10

So is the slope 2 ?

Answer 11

could you show your work?

Answer 12

no, to be honest I am guessing...seemed to me that the negative numbers cancel out the positive?? Am I correct that the slope is 2?

Answer 13

just follow the thing i typed up there if it is confusing ill type it a better way :P

Answer 14

Answer 15
