Answer 1

To find the equation of the line that represents the total population \( y \) in terms of years \( x \), we start with the current population and the rate of increase.

1. **Current Population**: The population is currently 2,760,065, which we can denote as \( y_0 = 2,760,065 \).
2. **Rate of Increase**: The population is increasing by 10,000 people per year. This translates to a slope (rate of change) of \( 10,000 \).

The equation of a line can be represented in the slope-intercept form \( y = mx + b \), where:
- \( m \) is the slope (rate of growth).
- \( b \) is the y-intercept (initial population).

Here, after \( x \) years, the population \( y \) will be:

\[
y = 10,000x + 2,760,065
\]

Where:
- \( 10,000x \) represents the increase in population after \( x \) years.
- \( 2,760,065 \) is the current population when \( x = 0 \).

Thus, the correct equation of the line representing the total population \( y \) in terms of years \( x \) is:

\[
y = 10,000x + 2,760,065
\]

So the correct response is:

**y = 10,000x + 2,760,065**.
