PLZ HELP! I will mark brainliest! Please include explanation!!!

So basically, this question is asking for the slope of the line, which is the distance between points. There are multiple ways to calculate it, one of the easiest but not always useful is rise over run. Basically, count up (positive) or down (negative) until you reach the same y as the next point. Then, count left (negative) or right (positive) to get to the point. In the end, you make it a fraction of the number of spaces it took to rise, over the number it took to run (side to side!) The other method will be taught to you soon if you don't already know, but its y2-y1/x2-x1, using two coordanites. I not very good with explaining things like this, so feel free to ask questions!
