Well, I will just use the equation mx + b = y, because I don't know the other forms.
So here, it is said that in the form mx + b = y or (y=mx + b, I would rather use the other one than this, the original one)
The m represents the slope of the line.
The b represents the y-intercept of the line, so we just put them.
mx + b = y
3x + -2/3 = y
3x - 2/3 = y (or others eliminate the denominator by multiplying 3 to the terms and becomes like this)
9x - 2 = 3y there are many other answers but I suggest you just pick one among them, I really don't know what should be the most appropriate one.
