Positive and negetive slope

=Activity - Name of Activity=
 * 1) Activity 1 Positive and negetive slope

Estimated Time
1 Hour

Materials/ Resources needed
Graph sheets

Prerequisites/Instructions, if any

 * 1) students should know what is slope/how to calculate if coordinates of the points on the are given
 * 2) basic operation of numbers

Process (How to do the activity)
Observe the following table and analyse the relation between X and Y (X,Y). You will find that in one case the value of Y goes on incresing with the value of x ,but in the other case the value of Y goes on decreasing with the value of x. In both the cases visualise the orientation of line segment. If the value of Y decrease with the value of X the line will have negetive slope If the value of Y increse with the value of X the line will have negetive slope

[This Geogebra applet helps in visualising Positive and negetive Slope]

Developmental Questions (What discussion questions)

 * 1) Observe the points on the graph sheet.Build the relation betwen X and Y values
 * 2) Record your observations
