Answer:
-2/3
Step-by-step explanation:
1. Slope formula, when you have two points on a line, is (y2-y1)/(x2-x1). (Note: To find the slope of a line, you only need two whole points, whether they're given to you, or you need to find them)
2. Use one point, we'll use (2,5), as (x1, y1), and the other point as (x2, y2). (Note: The order doesn't matter. You will always get the correct answer, even if you put (5,3) as (x1, y1))
3. Plug the points in for the values of the equation: (3-5)/(5-2) = -2/3
4. Your answer is -2/3 for the slope.
5. Easier solution: Count how many you move up (if you move down, you move negative up), and to the right (if you move left, you move negative right) between two points. This will not always work though, so don't rely on this method too much.
