In the slope-intercept form y = mx + b, what does m represent?

In the slope-intercept form y = mx + b, what does m represent?

• A. Y-intercept
• B. Slope
• C. X-intercept
• D. Constant term

Answer: (B)

The main idea is that m is the slope of the line, which tells how steep the line is and how y changes as x changes. Specifically, m is the amount y increases (or decreases) for each 1-unit increase in x. If m is positive, the line rises as you move to the right; if m is negative, it falls; if m is zero, the line is horizontal. The other part, b, is the y-intercept—the value of y when x is zero. So, m represents the slope.
