@Walkerman15  if you dont get it its ok

joel_the_boss · Answer

do you get it?

yanasidlinskiy · Answer

What's the question, really? I'm not understanding it.

joel_the_boss · Answer

you have to get into y=mx+b form then you have to solve it :3

joel_the_boss · Answer

x+3y = 7  I have the form I just need to solve it now  :( @Walkerman15  @YanaSidlinskiy

yanasidlinskiy · Answer

The first thing we do..Is...-x from both sides..Re-arrange the equation!!
-3y=-x+7.

joel_the_boss · Answer

I don't get any of this stuff can you explain :(

yanasidlinskiy · Answer

You're trying to get y by itself. Correct?

joel_the_boss · Answer

YES

ganeshie8 · Answer

$$\large x+3y = 7 $$

subtract -x both sides, you get 
$$3y =-x+ 7 $$

ganeshie8 · Answer

next divide 3 both sides

joel_the_boss · Answer

ok

joel_the_boss · Answer

x+y=2.33

ganeshie8 · Answer

$$\large   \dfrac{3y}{3} =\dfrac{-x}{3}+ \dfrac{7}{3}$$

ganeshie8 · Answer

$$\large   y =\dfrac{-1}{3}x+ \dfrac{7}{3}$$

ganeshie8 · Answer

is that the form you wanted ?

joel_the_boss · Answer

I think so it looks like other things ive been working on.

ganeshie8 · Answer

good, if u compare both the equations you will see :

slope = m = -1/3
y intercept = b = 7/3

joel_the_boss · Answer

y=-1/3x+7/3?
