please hurry im at the edge of finishing my class this could determine if i fail after this is a quiz then test i need extra score please

Answer 1

well you better get cracking then!

Answer 2

I'll do 3 of them for you (there's 3 types of questions here), then you can do the rest. I'll happily check your other answers, but I'm not going to do your test for you.

1. A (5,5), m=3.
The equation of a straight line is y=mx+c. We have m and a coordinate (x,y) so we can find c: 5=3*5+c so c=5-15=-10. Answer: y=3x-10.

3. G (4, 6), H (1, 5)
We aren't given m so we need to find it using coordinates (x0, y0) (x1, y1) (G and H):\[m=\dfrac{y_1-y_0}{x_1-x_9}=\dfrac{5-6}{1-4}=\dfrac{-1}{-3}=3\]Then like in 1, we use y=mx+c with one of the points, say G, 6=3*4+c so c=6-12=-6. Answer: y=3x-6.

10. E(3, 5), m = undefined
Not enough information to find it. y=mx+c for some constant c.

Answer 3

okay youl check behind me??

Answer 4

? hello

Answer 5

Post your answers and I'll check them.

Answer 6

i dont have them yet
i was hoping you would work me through it with me

Answer 7

I've shown you how to do them. Now repeat what I did for the others. As I said before, I'm not doing this for you, it's a lot of work.

Answer 8

no im not saying that im saying i do the problem and you tell me what i do right and wrong

Answer 9

Sure.

Answer 10

k i think i got this so i take the 5 and -2 and the 1/2 then i make it 5=1/2*-2?

Answer 11

Yes, but we need to find c. So we have 5=(1/2)*2+c. Rearrange to find C.

Answer 12

make the c by its self?

Answer 13

Yep :)

Answer 14

so-c=(1/2)*2-5

Answer 15

then -c=1-5

Answer 16

c=-1+5
c=4?

Answer 17

Sorry I've just seen you have your gradient wrong and I also wrote 2 instead of -2 before. m =2/5. So \[y=\dfrac{2}{5}x+c\]Using the coordinate (5,-2) we get \[5=\dfrac{2}{5}\times -2+c\]What is C?

Answer 18

no problem 22.5 is c

Answer 19

49 seconds ill rebump in

Answer 20

Not quite.\[c=5-\dfrac{-4}{5}=5+\dfrac{4}{5}=\dfrac{29}{5}\]

Answer 21

okay can u tell me how that happened lol lots of fractions just hit me

Answer 22

From before, \[5=\dfrac{2}{5}\times -2+c\]\[5=\dfrac{-2\times 2}{5}+c\]\[5=\dfrac{-4}{5}+c\]\[c=5-\dfrac{-4}{5}\] then just look at my last post.

Answer 23

oh okay i get it i think i can tackle the rest of these alone thank you im a fan!!

Answer 24

Glad to hear it, let me know if you have any more problems and I'll try my best to explain :) Good luck!
