Point slope form of a line:
where 
is your slope and 
is a point on your line.
For a line with a slope of 3/5 that passes through (10, -2)...
Let's plug these values into our formula.
Subtracting by a negative is the same thing as adding (the double negatives cancel), so let's simplify that.
There's our equation in point-slope form. (keep in mind that you're not going to want to distribute that 3/5 or subtract the 2 or anything. You want to keep it similar to the formula.
