Question
I have two questions about finding the slope of a line. First question: Is the formula Y2-Y1 over X2-X1? Second question: When I am given a line on a graph, how do I find Y1, Y2, X1, X2 to use in finding the slope?

yes on the first question.
On the second question, pick <u> any</u> two points on the line, label one of them y2, and one of them y1. It matters not in what order.
