Answer 3

You put the file location.

Answer 4

well i dont know hoe to post it:/

Answer 5

how*

Answer 6

is that an image file?

Answer 7

use the "Attach File" button, please

Answer 8

yup :/ idk y i did that nut i still dont know how to post the link to the graph its showing me on my page.

Answer 9

yes, next to equation and draw it says attach file

Answer 10

find the file you want, select it and hit "open"

Answer 11

do you know the equations for the lines...if you do, we do not need to see the graph

Answer 12

there we go:) well thank you @thekefentse

Answer 13

since we have one intersection point only, then we can conclude that we have one solution only

Answer 14

for A: you can see that the y-intercept (b) is = 6
for B: you can see that the y-intercept (b) is = 0

Answer 15

@Michele_Laino and the solution is (4,4) right?

Answer 16

or is it what @thekefentse said

Answer 17

please I'm checking your answer

Answer 18

please wait...

Answer 19

sorry

Answer 20

for A: to find the slope you need 2 points. In this case you can use \[(0,6) \] and \[(2,5)\] which gives you the following:
\[\frac{ 5-6 }{2-0 } = \frac{ -1}{ 2 }\]

Answer 21

the equation for A is as follows: \[y=-\frac{ 1 }{ 2 }x+6\]

Answer 22

you have to establish what are the x-coordinate and y-coordinate of the intersection point

Answer 23

I'm guessing you have to establish that by sight, yes?

Answer 24

it would be (4,4) thats where it intersects.

Answer 25

yes! @thekefentse

Answer 26

alright, so all you have to do now is prove that using the equations of the lines.

Answer 27

that's right! @WILD1

Answer 28

scratch that, all you need to do is get the equations.

Answer 29

to find the equation for B:
take any 2 points along the line \[(0,0)\] and \[(1,1)\]
Now do the slope formula: \[(x_{2} -x_{1}) / (y_{2}-y_{1})\]

@thekefentse @Michele_Laino sorry i got it now. thank yall both though yall have realy helped me today! thank yall again and medal for and can you medal @thekefentse thank you

Answer 31

Good luck!

Answer 32

thank you.

Answer 33

@thekefentse can you medal michele_laino?

Answer 34

i did ;)

Answer 35

thank you!

Answer 36

Anytime!

Answer 37

Thank you! @WILD1 @thekefentse
