The graph shows the altitude of a helicopter over time. A graph measuring altitude and time. A line runs through coordinates (0,
10,000) and (15, 4000) and shows a decrease in altitude as time increasesWhat is the slope of the line and what does it mean in this situation? The slope is –2000 . This means that the helicopter descends 2000 ft each minute. The slope is –400 . This means that the helicopter descends 400 ft each minute. The slope is 400. This means that the helicopter ascends 400 ft each minute. The slope is 2000. This means that the helicopter ascends 2000 ft each minute. 69 POINTS!!
To determine the slope, subtract the y coordinates from each other and the x coordinates as well. That gives us: 10000 - 4000 over 0 - 15, which simplifies to 6000 over -15. When divided, it results in -400. So, the slope amounts to -400. I hope this aids you!:D
The slope can be calculated with the formula y2 - y1 over x2 - x1. Substituting in gives us: 4,000 - 10,000 which equals -6,000 over 15 - 0, resulting in a value of 15. When this is simplified, we have -6,000 divided by 15 which equals -400.
Try this method: When a graph shifts right, replace 'x' with 'x' minus the number. When it shifts down, subtract the number from 'y'. So the final equation becomes: y = 4(x - 5)² - 18. The answer is A.
