Sure! I can help you with each of these questions one by one.
Question 1: Slope Descriptions (Select 3)
The concept of "slope" in mathematics typically refers to the "rise over run," which is a measure of how much a line rises or falls as it moves horizontally. The slope can be calculated using the coordinates of two points on a line (x1, y1) and (x2, y2).
The three correct answers from the responses provided are:
- y2−y1/x2−x1 - This is the correct formula for calculating slope.
- riserun - This represents rise (change in y) over run (change in x), which is another way to describe slope.
- change in y-value over change in x-value - This description accurately defines the concept of slope.
Question 2: Average Speed Calculations To answer this question, I would need the data for Larry's recorded times and distances for each hour. Please provide the data, and I can assist you in calculating the average speeds.
Question 3: Slope of the Line on the Graph Without the graph available, I cannot provide the correct answer. However, if you provide the coordinates or the context of the line, I can help you determine the slope.
Question 4: Comparing Speeds of Marathon Runners Similar to Question 2, I would need data regarding the distance each runner covered over a period of time to find their constant speeds. Please provide that data.
Question 5: Which Line has a Steeper Slope Without visual access to the graph or the specific lines mentioned, I can't determine which line has a steeper slope. Typically, you compare the slopes of the lines (rise/run), and the line with the greater absolute value of slope is considered steeper.
If you can provide specific details or data points for any of these questions, I would be more than happy to help you solve them!
