[00:00:00] Find the equation of the line passing through the given points. (2,-3) (4,-2)

Belinda B (Tutor)
[00:00:08] Welcome to Tutor.com ! Let's get started.

Natassja (Customer)
[00:00:18] ok

Belinda B (Tutor)
[00:00:25] would you like me to walk you through the steps?

Natassja (Customer)
[00:00:42] I know that I have to find the m and I got 1/2 for it

Belinda B (Tutor)
[00:00:52] ok let me take a look.
[00:01:20] yes 1/2 is correct

Natassja (Customer)
[00:01:28] and then use the y=mx+b solution but it's a multiple choice question and my solution doesn't match up

Belinda B (Tutor)
[00:01:38] ok no problem!
[00:01:58] so now we have to find the y-intercept

Natassja (Customer)
[00:01:58] I got -3=1/2(2)+b

Belinda B (Tutor)
[00:02:08] ok.

Natassja (Customer)
[00:02:21] and then -4=b

Belinda B (Tutor)
[00:02:33] thats correct.
[00:02:46] so initially, your y=mx+b is ...?
[00:03:00] y= (1/2) x -4 right?

Natassja (Customer)
[00:03:06] the answers I can choose from are: y=1/2x-7 or y=2x+3

Belinda B (Tutor)
[00:03:27] those are the only choices?

Natassja (Customer)
[00:03:29] yes

Belinda B (Tutor)
[00:04:04] can you check the points that are given and make sure you wrote down the right signs for them?

Natassja (Customer)
[00:04:32] they're right

Belinda B (Tutor)
[00:04:56] then looks like there a problem with the question. i can assure you your answer is correct, and you didnt make any mistakes

Natassja (Customer)
[00:05:13] okay /:

Belinda B (Tutor)
