Slope-Intercept Form

Summary
Understanding the slope-intercept form, y = mx + b, is crucial for graphing lines and solving algebraic equations efficiently.
• The slope-intercept form is selected by mathematicians for its utility in representing the equation of a line with y on one side.
• In the equation y = mx + b, 'm' represents the slope, and 'b' represents the y-intercept, providing immediate insights into the line's graph.
• Converting any line equation to slope-intercept form simplifies the visualization of its graph, using the y-intercept and slope steps.
• Practice problems demonstrate how to find points on a line and the slope of a line from different algebraic expressions.
• Understanding the characteristics of horizontal and vertical lines, including their slope and intercepts, is essential for graphing.
