At the end of this activity, you will be able to:[br] a.) find the slope of a line given two points [br] b.) identify the trend of the graph.

1. Type your desired coordinates of points A and B in the input box provided. Make sure that you have a slope that is positive, negative, zero and undefined. [br][br]2. Find the slope of a line given two points. Type your answer in the box provided. If the computed value of the slope is undefined, check the box corresponding to your answer.[br] The word "[b]CORRECT[/b]" will be displayed on the screen if your answer is RIGHT.[br][br]3. Explore and investigate the trend of the graph using this applet.[br]

1.) Find the slope of the line that passes through points A and B and describe the trend of the graph in each of the following conditions :[br]  a.) Set the [math]x_{_{_2}}[/math] which is greater than [math]x_{_{_1}}[/math] and [math]y_{_{_2}}[/math] which is greater than [math]y_{_{_1}}[/math] ,[br] b.) Set the [math]x_{_{_2}}[/math] which is less than [math]x_{_{_1}}[/math] and [math]y_{_{_2}}[/math] which is less than [math]y_{_{_1}}[/math] ,[br]  c.) Set the [math]x_{_{_2}}[/math] which is greater than [math]x_{_{_1}}[/math] and [math]y_{_{_2}}[/math] which is less than [math]y_{_{_1}}[/math] ,[br]  d.) Set the [math]x_{_{_2}}[/math] which is less than [math]x_{_{_1}}[/math] and [math]y_{_{_2}}[/math] which is greater than [math]y_{_{_1}}[/math] ,[br]  e.) Set the [math]y_{_{_2}}[/math] which is equal to [math]y_{_{_1}}[/math] and [math]x_{_{_2}}[/math] which is not equal to [math]x_{_{_1}}[/math] , and[br]  f.) Set the [math]x_{_{_2}}[/math] which is equal to [math]x_{_{_1}}[/math] and [math]y_{_{_2}}[/math] which is not equal to [math]y_{_{_1}}[/math] .[br][br]2. How did you find the slope of a line given two points?[br][br]3. How do you relate the slope of the line to the trend of the graph/ line?
