Let's analyze the data provided in order to answer the questions:
-
The distance traveled (y) per minute (x) can be found by calculating the slope of the line formed by the data points.
To find the slope (rate of change of distance with respect to time), we need to calculate how much distance is traveled for each minute. We can do this using one of the data pairs:
- For example, (4, 76) to (3, 57): \[ \text{slope} = \frac{76 - 57}{4 - 3} = \frac{19}{1} = 19 \] This rate is consistent across all points.
Thus, the average rate of distance traveled is 19 meters per minute.
Responses: a. Every minute 19 meters are traveled.
-
Next, we need to find the equation showing the relationship between x and y. The general linear equation is given by: \[ y = mx + b \]
Here, \(m\) (the slope) is 19 and \(b\) (the y-intercept) can be calculated by substituting a point into the equation. Choosing (4, 76): \[ 76 = 19(4) + b \quad \Rightarrow \quad 76 = 76 + b \quad \Rightarrow \quad b = 0 \]
So, the relationship can be expressed as: \[ y = 19x \]
Responses: b. Write an equation to show the relationship between x and y: y=19x.
- Next, we need to determine if this relationship is proportional or non-proportional. Since the equation passes through the origin (0,0) and the y-intercept is 0, we can conclude that this is a proportional relationship.
Responses: c. This relationship is proportional because the y-intercept is (0, 0).
Final Responses:
a. Every minute 19 meters are traveled.
b. Write an equation to show the relationship between x and y: y=19x.
c. This relationship is proportional because the y-intercept is (0, 0).
