If I have a line that connects these two points and if i have a line that connects two points this is the slope of that line. the change in distance is right over here.Change in y=100 m and our change in time is this right over here so our change in time is equal to 9.58 seconds we start with 0, we goto 9.58 seconds another way to think about it - the rise over the run you might have heard in your algebra class.
