Question

The slope of the line below is 2. Use the coordinates of the labeled point to find the point-slope equation of the line. (-2,-5) those are the points i was given
A. y + 5 = -2(x + 2)
B. y - 5 = 2(x - 2)
C. y - 5 = -2(x - 2)
D. y + 5 = 2(x + 2)
someone please help!

Answer 1

this is point slope formula
y1-y=m(x1-x)
y and x are the points and m is still the slope

Answer 2

Would it be D?

Answer 3

you get too confused with the formulas hold up let me rewrite it in a different way

Answer 4

ok.. Sorry i am not good at math.

Answer 5

does it make more sense now?

Answer 6

kind of so it would be B?

Answer 7

Could you run through another one like this? but walk me step by step just to make sure i understand it correctly.?

Answer 8

actually nvm lol you were right the first time and I was wrong

Answer 9

it is D because minus and a negative become a plus

Answer 10

and sure

Answer 11

so its y+5=2(x+2) correct?

Answer 12

yes

Answer 13

Sweet!!! 6 more questions on this test and its done xD

Answer 14

ok lol you better get an A on that test

Answer 15

i won't... I got 5 wrong.. So I got everything else fine. but if i get 1 more wrong i don't think i'll pass and i dont want to do this test again.

Answer 16

my God are those 5 questions part of the one I helped you with?

Answer 17

Did you help me with one about what are the correct statements bout slope formula?

Answer 18

I think so (I wasnt sure about C)

Answer 19

C was wrong.. It was Rise/run and y1-y0/x1-x0 those were the only 2 answers i needed. Otherwise everything else was fine!

Answer 20

but it doesn't give me credit if i miss one. it marks the whole problem wrong...

Answer 21

other than that you have been a great help!

Answer 22

wow ok I feel guilty now xD but either way ask your teacher and give her the same reasons why I think C should have been part of it and maybe you either prove him/her wrong or get at least credit

Answer 23

Ok, i'll try to reason with the internet. I take it online. lol dont feel guilty. xD

Answer 24

oh virtual classes... well still try to reason with whoever gave you the lesson on slope before you took the test. And post the next question lol lets try to get a passing grade at least

Answer 25

ok hold on let me get the next question! lol

Answer 26

this is my only virtual class though
