What is the percent increase when 7,200 increases by 1,800? 20 percent
25 percent
54 percent
80 percent

25 percent

Step-by-step explanation:

7200 divided by 1800 is 25

The y - intercept is where the line cuts the y- axis... or vertical axis. this is her height when the observer first sees her

pick 2 points on the line and find the slope

say (0, 4500) and (1, 3000)

slope = change in altitude/change in time
= (3000 - 45000)/(1 - 0)

the x intercept is where the line cuts the x-axis.. horizontal axis

it shows the time it took the skydiver to travel from 4500 feet to the ground.

Hope it helps
