Graphing Lines Using Point-Slope Form
Graphing lines with point-slope form involves identifying a point and slope, plotting the point, and using the slope to determine the line’s direction and placement.
6.1 Plotting the Point
Plotting the point is the first step in graphing a line using point-slope form. Identify the coordinates (x₁, y₁) from the equation and locate them on the graph.

Once the point is plotted, the slope (m) determines the line’s direction. A positive slope indicates the line rises from left to right, while a negative slope shows it falls. The slope’s value represents the steepness: a larger absolute value means a steeper line. To apply the slope, move m units up or down for every 1 unit right or left from the plotted point. For example, a slope of 2 means moving 2 units up for each unit right. This step ensures the line’s direction aligns with the slope’s value, helping to accurately graph equations using point-slope form effectively.
6.3 Drawing the Line Accurately
Drawing the line accurately requires careful extension beyond the plotted points. Use the slope to guide the direction, ensuring consistency. A positive slope rises from left to right, while a negative slope falls. For precision, use a ruler to extend the line smoothly. If needed, plot additional points along the line to maintain accuracy. Always double-check the slope to ensure the line’s direction remains consistent. This step ensures the final graph is clear and precise, making it easier to interpret and work with for further analysis or problem-solving in point-slope form worksheets.
