How to Graph Linear Equations (Slope-Intercept Form)

Subject: Mathematics

Book: Maths Mastery

The slope-intercept form y = mx + b reveals a line’s slope (m) and y-intercept (b). For example, if y = 2x + 3, the slope is 2 and the line intercepts the y-axis at (0, 3). You can quickly plot the point (0, b) on the y-axis, then use slope rise/run to locate more points. Graphing linear equations is foundational in analyzing trends, relationships between variables, or business metrics (like cost vs. revenue). Mastery of slope-intercept form helps interpret how changes in x impact y, essential for linear modeling and everyday problem-solving involving direct variation.
