What is the slope of the line represented by the equation y = 2x + 1?

The concept of slope in the equation of a line is derived from the slope-intercept form of a linear equation, which is written as (y = mx + b). In this format, (m) represents the slope of the line, and (b) represents the y-intercept, which is the point where the line crosses the y-axis.

In the equation provided, (y = 2x + 1), you can identify the slope by looking at the coefficient of (x). Here, the coefficient of (x) is (2). Thus, the slope of the line is (2). This means that for every unit increase in (x), (y) increases by (2) units, indicating the steepness and direction of the line.

The other choices reflect incorrect slopes based on the values given. Understanding the structure of the linear equation and identifying the coefficients correctly is crucial to determining the slope accurately.
