You can find slope of a line through two different ways first is by first find the y coordinate difference between one coordinate and another on the line to the right of it. so for example the y coordinate difference between (2,3) and (3,5) is 2 and then find the x difference which is 1 after that we first divide the y difference by the x difference which is 2/1 or just 2 then if needed we simplify it. Another example of this is if we have two order pair (4,2) and (5, 3,) which are points close to 1 after the other on a linear relation line the y difference is 1 and the x difference 1 so the slope of the line is 1/1 or just 1. Another way to do this to same as we do in the first way up until find the difference but instead of subtracting we instead look on a graph of the line and find how many numbers we go up by to reach the other point and the rest is the same. Good things to remember is if there is no difference in x or it is just a vertical line the slop is undefined if the line is horizontal the slop is 0.
