Slope = y2 - y1 = rise . x2 – x1 run . Students should also recall that a positive slope rises from left to right, a negative slope falls from left to right, a slope of zero is a horizontal line, and a vertical line has an undefined slope. Complete the table and then graph the line for the equation y = x – 4. ...

Slope Activity for Algebra I - Texas Instruments
Students should know two ways to find slope: Rise and y1- y2. Run x1- x2. Break students up into groups of four and have them log into navigator. The teacher should plot a line using activity center and have one group pick out four nice points so the rest of the class can determine the slope by rise over run and by using the slope formula.

Slope is the ratio of vertical change to horizontal change. m = rise = y2 ( y1 = (y run x2 ( x1 (x. Rise is the amount of change on the y-axis and run is the amount of change on the x-axis. A line with positive slope “climbs up” when viewing from left to right and a line with negative slope “slides down” from left to right.
