Is the second paragraph meant to throw you off??? Because the answer to the question does not rely on the information based from the second paragraph...
Anyway, we know that the turtle started from (0, 0) and moved to (10, 8). Let's assume that (0, 0) is (x1, y1), and that (10, 8) is (x2, y2) for the sake of calculations.
To find how far the turtle moved to the right (along the x-axis) we take x1 from x2:
 x2 - x1 = 10 - 0
 = 10 = x2
 ***this is the "run"
To find how far the turtle moved upwards (along the y-axis) we take y1 from y2:
 y2 - y1 = 8 - 0
 = 8 = y2
 ***this is the "rise"
Notice that when something moves away from the origin the distance it traveled along the x-axis and y-axis is the same as its final position (or coordinates to where it traveled to).
Therefore, the,
 slope = rise / run
 = x2 / y2
 = 10 / 8
 = 5 / 4 (preferable for use)
 = 1.25
        
                    
             
        
        
        
Well, there's many equations that represent real world situations. These equations we use a lot in engineering. For example, something fundamental is that we can calculate the velocity of something by knowing it's acceleration by taking the integral of the acceleration.
