Math Help - Slope = Rate of Change - Line Graph Game L-CRD2 Tips: - Press the 't' key to see a graph that demonstrates the following example. - The slope (average rate of change) from a point P(-2,-3) to a point Q(1,4) is calculated as slope = (rise)divided by(run) = (change in y)/(change in x) = (4-(-3))/(1-(-2)) = (7)/(3). - Press the 'y' key to restart the game. - The rate of change in a relation such as y=mx and its ordered pairs (x,y) can be measured by the ratio = (change in y)/(change in x) = m = slope. Generally, the idea is that the average rate = (y2-y1)/(x2-x1) = m = slope. - It may take a minute to load the game at dial-up speeds. - The game can be played using the mouse by itself or using the keyboard by itself. - If the game doesn't respond to keyboard input, click inside the game area to reset the game's focus. - Adjust the game's speed by pressing the + or - key repeatedly. |
