What is the slope-intercept formula of a line?

• A. Y = mx
• B. Y = mx + b
• C. Y = m + x
• D. Y = bx + m

Answer: (B)

The slope-intercept formula of a line is expressed as \( Y = mx + b \). In this formula, \( m \) represents the slope of the line, indicating how steep the line is and the direction it moves (upward or downward) as it moves from left to right on a graph. The \( b \) term is the y-intercept, which is the point where the line crosses the y-axis. This formula allows for easy graphing of linear equations because it directly shows the slope and the y-intercept, making it straightforward to visualize the relationship between the variables. The other options do not accurately reflect the components needed to define a linear equation in slope-intercept form. For instance, the first option lacks the y-intercept term, while another option incorrectly swaps the roles of \( m \) and \( b \) or uses the wrong arrangement of terms completely. Overall, the accurate representation of the slope-intercept formula is crucial for understanding linear relationships in mathematics.
