Question

Put the equations in slope-intercept form and then graph it.

3x + 7y = 2
3x - 4y = 13

Answer 1

Hey @hkskqgywi ......Do you know the standard line equation......
y = mx + c
You just need to compare both and plot the graph

PS:Mate you have a way difficult name... :p

Answer 2

Is it done????

Answer 3

Sorry, I was working on a different problem of mine. No, it isn't because I have a difficult time of this kind of algebra... I know the standard equation I just don't know how to put those equations into that

Answer 4

Okay.....
3x + 7y = 2
7y=2-3x
y=2/7-3/7x
So, now on comparing, c=2/7, m=-3/7

Similarly, do it yourself for second one....
3x - 4y = 13

Answer 5

So 3x - 4y = 13
4y = 13 + 3x
y = 13/4 + 3/4x??

Answer 6

Yup...Now compare for the values of c & m

Answer 7

c=13/4 & m=3/4??

But is that many fractions okay to graph?? because my question says to graph them to find the solution for the system of equations..

Answer 8

Yup...There no problem......Or wait...Your question if augmented might become......Find the solution of the equations....

Answer 9

all I have to do is put them in slope intercept form and then graph them to FIND the solutions. Which for system of equations I don't know if they want me to shade a part or not... I hate algebra lol.

Answer 10

Man....You are making me confused too....Just find some values of x & y for each equations & plot their graph....Point where they intercept is the solution......

Answer 11

I am a girl by the way. Ill just try to graph them and see where they point to find the solution

Answer 12

Sorrryy....Am really sorry.....Pardon me......

Answer 13

Isn't the X supposed to be in the other place?
y = mX + b (my teacher always told us it was b).

Answer 14

Its the same c i.e. the intercept on Y-Axis.....I researched & found out that in british systems its c & in US its b.....

Answer 15

so in the slope intercept form you demonstrated for me (thank you by the way),
in y= 2/7 - 3/7x
-3/7x is going to be the x-intercept? and then 2/7 is going to be the y-intercept?

Answer 16

Oki...Sis...Take a look at this.....Also your solution is x=3 & y=-1

Answer 17

I have to graph it on this http://taylormath.pbworks.com/f/1193085651/f-206-15-ex-1.gif

Answer 18

When you plot it...It should look like this...

Answer 19

Okay, thank you.

Answer 20

Anytime...^_^
