What is the slope-intercept form of a linear equation?

• A. y = mx
• B. y = bx + a
• C. y = mx + b
• D. y = ax + b

Answer: (C)

The slope-intercept form of a linear equation is represented as \( y = mx + b \). In this format, \( m \) denotes the slope of the line, which indicates how steep the line is and in which direction it ascends or descends. The value \( b \) represents the y-intercept, which is the point where the line crosses the y-axis. This form is particularly useful because it allows for easy visualization and interpretation of a linear relationship. By knowing the slope, one can determine how much \( y \) increases or decreases when \( x \) changes. Additionally, the y-intercept provides a starting point for graphing the line. In summary, the equation \( y = mx + b \) clearly delineates both the slope and the intercept, making it a fundamental representation in algebra for linear equations.

The slope-intercept form of a linear equation is represented as ( y = mx + b ). In this format, ( m ) denotes the slope of the line, which indicates how steep the line is and in which direction it ascends or descends. The value ( b ) represents the y-intercept, which is the point where the line crosses the y-axis.
