Final answer:
The slope of the snowboard jump is 0.25.
Step-by-step explanation:
To find the slope of the snowboard jump, we can use the formula for slope, which is rise over run. The rise is given as 1.25 m and the run is given as 5 m. So the slope can be calculated as 1.25/5 = 0.25. Therefore, the correct answer is option A) 0.25.
