I NEED HELP. PLEASE

I do not understand pointslope and standard form. Please help me.

Can you be more specific with your question?
Is the "standard form" y = mx + b ? 
Example: point slope is y+5=4/1(x+3)
y + 5 = 4(x+3)
y + 5 = 4x + 12
subtract 5 on both sides.
y = 4x + 7
subtract 4x on both sides.
4x + y = 7
divide both sides by 1.
[[ 4x  y = 7 ]]
You can search on websites and have some examples like this one 
Thanks!
How would you know whether to add or subtract? 
Solve for y = mx + b or y  y1 = m (m  x1). Your line will be in slope intercept form.
Now add/subtract/multiply/divide in order to get to Ax + By = C, where A,B&C are nonfractions and A>0.
For example: Write the equation of a line in standard form that has a slope of 4 and passes through (3,5).
y  y1 = m (x  x1)
y  5 = 4 (x  (3))
y  5 = 4x + 12
Add 5 to both sides.
y = 4x + 17
Subtract 4x from both sides to get the variables on the same side.
4x + y = 17
The pattern for Standard Form shows that the coefficient with x can't be negative when it expresses A>0. So, multiply everything by 1, keeping in mind you can do anything to an equation and it will remain true as long as you do it to both sides.
1(4x + y = 17)
4x  y = 17
brightstorm is a website you can get all of this. I got all of this from it but i forgot how to put a link on it 
Thank you.
