slope and y intercept form of these two problems?

Y-5=1/3(x-9)

2y+6a-4x=0

• Math -

For the second one I have this but I'm not sure what to do next

Add 4x to both sides, so you would have 2y+6a=4x

Then I divided 2y by 2 and 4x by 2 and got y+6a=4x

Next I subtracted 6a from both sides and got y=2x-6a

Am I right so far? If so what do I do next?

• Math -

2nd:

2y + 6a - 4x = 0
you want to "isolate" the y, so everybody else to the other side
2y = 4x - 6a
divide each term by 2 , (you only divided one term and not the others)
y = 2x - 3a

the 1st:

y - 5 = (1/3)(x-9)
y = (1/3)x - 3 + 5
y = (1/3)x + 2
