# Activity - Name of Activity

- Activity 1
**Positive and negetive slope**

## Estimated Time

1 Hour

## Materials/ Resources needed

Graph sheets

## Prerequisites/Instructions, if any

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

## Multimedia resources

## Website interactives/ links/ simulations/ Geogebra Applets

## 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)

- Observe the points on the graph sheet.Build the relation betwen X and Y values
- Record your observations
