Answer 1

Well first you must find the slope

Answer 2

Do you know how?

Answer 3

or do you need help finding it?

Answer 4

i need help finding it.

Answer 5

Okay, so to find slope you must do
y2 - y1 over x2 - x1

Answer 6

so start out by doing -1 - 7. what does that equal?

Answer 7

-8

Answer 8

or sorry, I mean -1 - 5

Answer 9

-6

Answer 10

Ok, now -4 - 7

Answer 11

-11

Answer 12

so now you know your slope is 6/11, it is positive because the two negative numbers cancel each other out

Answer 13

so you understand so far?

Answer 14

yes i do

Answer 15

Ok, from the answers they give us we know they want us to use the coordinates (-4,-1) Point slope form is y-y1 = m (x-x1)

Answer 16

m= slope, and we know our slope is 6/11

Answer 17

so plug it in and we have y - y1 = 6/11(x-x1)

Answer 18

What is your y-axis for the coordinates (-4,-1)?

Answer 19

do you mean out of those 2 numbers? if so it is -1.

Answer 20

yes! so plugging it in we have
y+1= 6/11(x-x1)
Do you understand so far?

Answer 21

Now plugging in for x we get
y+1 = 6/11(x+4)

Answer 22

Now, which of the answers looks exactly like this one?

Answer 23

So its b?

Answer 24

yes :)
