y2-y1
___
x2-x1
first find any two points on a line
then take the second point's (y) and subtract it from the first points (y)
then divide by the second (x) subtracted by the first points (x) like the (y)
the first (x,y) is the left dot of your two dots and the second (x,y) is the right dot of the two
the result is the slope of the line of the graph
ex. (8,7) (13,11)
(11-7) / (13-8)
slope = 4 / 5
(4up and 5 over)
hope this helped :)

To graph an equation that is not in slope-intercept form, you can use the process of finding points on the graph and plotting them. Choose a few x-values, plug them into the equation to find the corresponding y-values, and plot those points on the graph. Then, connect the points with a smooth line to complete the graph.
Your x and y intercepts give you two points on the line of the graph. Use these two points in the slope equation m = (y2-y1)/(x2-x1), and that gives you the slope.

A graph is more informative than an equation because a graph is easier to interpret visually, and find all the points and line them up, rather than just a slope which shows no points(data).
