Math Problem Statement
Solution
To find the best linear equation that models the population of the town from 2000 to 2010 based on the scatter plot, we need to determine the slope (rate of change) and y-intercept of the line that best fits the data.
Step 1: Identify two points from the graph
From the scatter plot, two clear points can be:
- At (Year 2000), thousand.
- At (Year 2010), thousand.
Step 2: Calculate the slope
The slope of a linear equation is given by:
So, the slope .
Step 3: Identify the y-intercept
The y-intercept is the population at , which is 1.12.
Step 4: Form the equation
The equation of the line is:
Conclusion:
The correct linear equation that models the town's population from 2000 to 2010 is:
This matches the second option from the given choices.
