Graphing with a Point and Slope
Graph a line using a known point and the slope in Grade 9 Algebra. Plot the given point, then use rise-over-run to locate additional points along the line.
Key Concepts
Property To graph a line with a known slope and point, first plot the given point. Then, use the slope (rise over run) from that point to find a second point and draw a line through both.
Examples Graph a line with slope 4 and point (3, 5): Plot (3, 5). From there, go up 4 and right 1 to find point (4, 9). Draw the line. Graph a line with slope $ \frac{2}{3}$ and point (2, 4): Plot (2, 4). From there, go down 2 and right 3 to find point (5, 2). Draw the line.
Explanation It is like a treasure map! Start at your given point ('X' marks the spot). The slope tells you where to go next: 'rise' is your up/down count, and 'run' is your right count. Plot your second point where you land and connect the dots to reveal the treasure path!
