Question

write an equation point-slope form for the line through the given point with the given slope. (-4,-2); m= - 1/2

Answer 1

do you remember what point slope form is?
\[y-y=m(x-x)\]

Answer 2

no im not sure i totally forgot @lonnie455rich

Answer 3

well. the form I posted is point slope. you know that m = slope right?

Answer 4

nooooo

Answer 5

well it is. knowing all this, take a stab at it and ill let you know if you have any mistakes

Answer 6

y+7=-0.54(x-4)

Answer 7

@lonnie455rich

Answer 8

where did you get those numbers from. I see
(-4,-2) as points
and slope is -1/2

Answer 9

i was doing the wrong question okay i got
y+2=-1/2(x-4)

Answer 10

is it right

Answer 11

almost. think about your sign on the (x-4) you got it correct on the left side with the y. why didn't you on the right?

Answer 12

+ sign ?

Answer 13

yes because if you write it all out you get
\[y-(-2)=-1/2(x-(-4)\]
then if you simplify what would you get

Answer 14

y+2=-1/2(x+4)

Answer 15

perfect.

Answer 16

thanksss can you help with some more ?

Answer 17

sure.

Answer 18

write an equation point-slope form for the line through the given point with the given slope. (4-7);m=-0.54

my answer = y-7==0.54(x-4) right ?

Answer 19

with the points
(4,-7) and m=-.54
looks like I see 1-2 mistakes depending on if one of those equal signs is supposed to be a negative sign. think about the -7 and what we did earlier

Answer 20

okay so it would be
y+7=-0.54(x+4)

Answer 21

well you made a mistake there. think about your sign on 4

Answer 22

- right ? i always get my signs confused

Answer 23

it will only be positive there if your point is negative because of the point slope formula

Answer 24

whenever I learn any kind of new technique or equation. on every problem I do. I just write Eq: then write out the equation
then I solve the problem. helps me remember things.

Answer 25

okay thanks thats better because i get confused a lot and im not so good in math you know....

Answer 26

math is arguably 1st-2nd of the hardest subjects there is for any given level of schooling. don't worry, just takes practice.

Answer 27

thank you for helping me i understand it better now ( : yes im going to pratice now

Answer 28

glad to hear. good luck
