Question

Last question for the night :D
Consider the line that passes through the point (3, -6) and has a slope of 4.

Part 1: Write the equation of this line using point-slope form.
Part 2: Using your equation from part 1, rewrite this equation in slope-intercept form. Make sure to show all of your work.
Part 3: Using your equation from part 2, rewrite this equation in standard form. Make sure to show all of your work.

Answer 1

you familiar with the 3 forms of line ?

1. point-slope form
2. slope-intercept form
3. standard form

Answer 2

y - y1 = m(x-x1) Point slope form

Answer 3

slope m = -6/3

Answer 4

m = -2

Answer 5

x1 = 3
y1 = -6
m = -2

Answer 6

putting back inot original formula

y - (-6) = -2(x-3)

now rearranging

y = -2(x-3) - 6

simplified

y = -2x + 6 - 6

simplied further

y = -2x

Answer 7

http://openstudy.com/study# is that right?

Answer 8

huh?

Answer 9

sorry how do u do the @ thing, get ganeshie to check it

Answer 10

Okay write which part is which part like part 1: part 2: ...?

Answer 11

@ganeshie8

Answer 12

how did u do that?

Answer 13

just @ and write their name

Answer 14

ok thanks

Answer 15

hopefully he checks it. need it to be right. thanks for medal

Answer 16

looks good :)

Answer 17

oly one thing missing is, slope is given as 4 here . not -2. m = 4 :)

Answer 18

yeah i know but if u do the problem it gives -2

Answer 19

hmm lets simply use the given slope :)

Answer 20

m = rise / run right?

m = -6/3

Answer 21

Part 1: Write the equation of this line using point-slope form.
y - (-6) = 4(x-3)

Answer 22

Part 1 is done. Move to Part II.

Answer 23

ok

Answer 24

Part 2: Using your equation from part 1, rewrite this equation in slope-intercept form. Make sure to show all of your work.
y - (-6) = 4(x-3)
y + 6 = 4x - 12
y = 4x - 18

Answer 25

Part 2 done. Move to Part III :)

Answer 26

y = mx + b

Answer 27

^yes thats for Part II.

I am sure you can do Part III. just rearrange the equation from Part II to standard form @InstagramDoll

Answer 28

so u use y = 4x - 18 and put it into standard form is that right?

Answer 29

exactly.... :)

Answer 30

which gets rearranged to:

4x - y - 18 = 0

is that right?

Answer 31

yes, take the 18 to other side :-

Part 3: Using your equation from part 2, rewrite this equation in standard form. Make sure to show all of your work.
y = 4x - 18
4x - y = 18

Answer 32

Putting it all together, just for clarity... Make sure you understand this and work it on your own again @InstagramDoll

Part 1: Write the equation of this line using point-slope form.
y - y1 = m(x-x1)
y - (-6) = 4(x-3)

Part 2: Using your equation from part 1, rewrite this equation in slope-intercept form. Make sure to show all of your work.
y - (-6) = 4(x-3)
y + 6 = 4x - 12
y = 4x - 18

Part 3: Using your equation from part 2, rewrite this equation in standard form. Make sure to show all of your work.
y = 4x - 18
4x - y = 18

Answer 33

ok thanks,

Answer 34

I needa study all this tomorrow morning, lol i just wanted to quickly finish cause its 4:27 am and i needa be in bed. So the full answer would be .

1;
y - (-6) = 4(x-3)

2;
y - (-6) = 4(x-3)
y + 6 = 4x - 12
y = 4x - 18

3;
y = 4x - 18
4x - y = 18

Answer 35

Thanks @ganeshie8 & @Helpmeplease99 for the help.

Answer 36

you certainlny deserve some good sleep.... after so much studying... good night :)

Answer 37

Goodnight to you both too.
