To calculate the slope, you can use the formula

In this case,

Your slope is 0/3, which does not make sense so there should be something incorrect about your points.
6a+15+5a-10
11a+5 is the answer :D
mutiply 3 to 2a and 5 / 5 to a and -2 you will get 6a+15+5a-10 then 6a+5a and 15-10 would be 11a+5
sorry I'm not good at explaining, ask me if you got a question. :D
