Answer: 10
Step by Step Solution:
You have x and y as your axis’s and that as your table with x being time and y being percent bounded. As for that you got (0, 0) and (5, 50).
Then you plug those numbers into the equation to finding slope: m = y2 - y1 / x2 - x1 to have m = 50 - 0 / 5 - 0
Then you have to simply the equation to have m = 50 / 5 and then you divide them as the line of a fractions means division and you will have m = 10
