Answer 2

First, I believe you have to decide what points you want to use to get the slope of -1/2

Answer 3

could this help me?

Answer 4

some points could be (4,-1) (6,-2)

Answer 5

so how do i write an equation of a line that has a slope of -1/2 in point-slope form, and slope-intercept form.

Answer 6

well what is y1

Answer 7

-1
?

Answer 8

yup, so so far we have y+1= -1/2 x - x1 what is x1?

Answer 9

4

Answer 10

?

Answer 11

yup, so then we have y+1=-1/2 x -4

Answer 12

thats it for a? we don't have to solve?!
now how do we do b? y=mx+b

Answer 13

what did you have to do for 13 on your last question?

Answer 14

what do you mean?

Answer 15

you have to subtract 1 from -4

Answer 16

so its -5

Answer 17

so then what do you get?

Answer 18

-5 ?

Answer 19

so then its y=-1/2 x - 5

Answer 20

and your done!

Answer 21

now i have 10 problems of standard form to do and 15 problems to do of parallel and perpendicular lines but i don't want to keep bothering you.

Answer 22

oh, don't worry, it will help me! I am in "Enriched Algebra" and I just learned that, and I understand it really well - helping you will help me study and practice!
