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

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
