Oh my god, i am so sorry i did not mean to reply to your comment Hiylin Link, I mean to post a new answer and sorry if i offend you in anyway :(
Tip for the person who posted this question:
The form of standard form is ax+by=c
so you should just plug in values from the slope intercept equation, and put it in a way that would fit the standard form.
Slope intercept is y=mx+B
and thus if you have a line that contains a slope of 1/2 and passes through the point of (-2,3), you would need to find your equation first, and put it into slope intercept, and then change it and put it as standard form!
