The equation $y = 2x + 3$ represents a linear equation in slope-intercept form, where:

• $y$ is the dependent variable.
• $x$ is the independent variable.
• The coefficient of $x$, which is 2, is the slope of the line.
• The constant term, 3, is the y-intercept, where the line crosses the y-axis.

Characteristics of the Line:

1. Slope (m): The slope is 2, meaning the line rises 2 units vertically for every 1 unit it moves horizontally.
2. Y-Intercept (b): The y-intercept is 3, so the line crosses the y-axis at the point (0, 3).

Graph of the Line:

To graph the equation, you can:

1. Start at the y-intercept (0, 3) on the y-axis.
2. Use the slope to find another point: from (0, 3), move 2 units up and 1 unit to the right to reach the point (1, 5).
3. Draw a straight line through these points.
