Question

Which is an equation in point-slope form for the given point and slope?

Point: (7, 4); Slope: 6

A. y – 7 = 6(x + 4)

B. y – 4 = 6(x – 7)

C. y – 4 = 6(x + 7)

D. y + 4 = 6(x – 7)

Answer 1

point slope form: y - y1 = m(x - x1)
when m = slope and given the point (x1, y1)

Answer 2

Is it B?

Answer 3

yep :)

Answer 4

Ok :) Can you help with a few more? just 3 or 2

Answer 5

sure :)

Answer 6

Oh, and thanks!

Answer 7

Which is an equation in point-slope form for the given point and slope?
Point: (–2, 4); Slope: 5

A. y + 4 = 5x – 10
B. y – 4 = 5(x – 2)
C. y – 4 = 5(x + 2)
D. y + 4 = 5(x + 2)

Either B or C, not sure.

Answer 8

y - 4 = 5(x - (-2)) --> y - 4 = 5(x + 2)
so C would be correct :)

Answer 9

Ok, thanks :)
Which is an equation in point-slope form for the given point and slope? Point: (1, –7); Slope: -2/3
A. y –7 = 2/3(x – 1)
B. y –7 = -2/3(x + 1)
C. y + 7 = 2/3(x + 1)
D. y + 7 = -2/3(x – 1)

Is it D?

Answer 10

correct! :D

Answer 11

Yay! :D Thanks! Last one:

A yearbook printer charges based on the number of pages printed. Here is a table that shows the cost of some recent yearbooks.

Number of pages |50|100|150|200|
Cost |1.55|2.25|2.95|3.65|

Which equation gives the cost, y, in terms of the number of pages, x?

A. y = 0.014x + 49.15
B. y = 0.014x + 1.55
C. y = 0.014x + 0.85
D. y = 58.8x + 0.85

B?

Answer 12

not quite...
the form is y = mx + b
you understood that m=0.014 good :)
now for b is when x=0
so when x=0 --> 1.55-0.7 =

Answer 13

Umm.. hold on, let me think about it, can you wait a sec?

Answer 14

sure :)

Answer 15

Thanks!

Answer 16

So.. is it A?

Answer 17

what is 1.55-0.7 =

Answer 18

0.85

Answer 19

Wait.. oooh, so its C? :/

Answer 20

yep :)

Answer 21

Oh, I get it now, it is C! Sorry :P I'm not good at graphs, slopes, and intercepts. Thanks a lot!

Answer 22

What grade are you in, if there is anything I can help you with?

Answer 23

hey jigglypuff314 can you help me with a problem

Well.. I guess both :P

Answer 27

http://openstudy.com/users/jigglypuff314
would be the link to my profile... but I don't think it's working :P

Answer 28

Btw, is that pic by your name you?

Answer 29

It works :) But how can I get to you every time I close my computer or log off?

Answer 30

Actually, it doesn't work.
