Title Slide

Welcome to this tutorial on Graphing Lines simulation.
Slide Number 2

Learning Objectives

Demonstrate an interactive PhET simulation, Graphing Lines

In this tutorial, we will demonstrate, Graphing Lines, an interactive PhET simulation.
Slide Number 3

Pre-requisites

To follow this tutorial,

Learner should be familiar with topics in high school mathematics.

Slide Number 4

System Requirements

Ubuntu Linux OS version 14.04

Java version 1.7.0

Firefox Web Browser 53. 02.2

Here I am using,

Ubuntu Linux OS version 14.04

Java version 1.7

Firefox Web Browser version 53.02.2

Slide Number 5

Learning Goals

Using this simulation we will learn,

About Cartesian coordinate system

How to calculate the slope of a graphed line

To save the plotted lines

How to change the slope and intercept of the line

How, changing variables in a linear equation will affect the line.

Slide Number 6

Linear Equation

y=mx+b

point to m and b.

An equation with two variables x and y is a Linear equation. y=mx+b

Here m is slope of the line and b is intercept.

Slope signifies rate of change of y value with respect to x value.

y-intercept is y value when x=0

Let us begin the demonstration.

Point to Slope, Hide lines, Hide grid check boxes. Below the formula box, we have Slope, Hide lines and Hide grid check boxes.
Point to the check boxes. If we click on, Hide lines and Hide grid check boxes, graph and grid are hidden.

Automatically, Slope check box is disabled.

Uncheck, Hide lines and Hide grid check boxes Let's uncheck Hide lines and Hide grid check boxes to enable Slope check box.
Point to the Graph and slope. Notice that Graph displays value of the slope.

Observe that on moving purple and yellow points, x1, y1 and x2, y2 values can be changed.

Point to purple and yellow points on the line.

Click and drag them on the line.

As we move the points, slope of the line changes.

Observe the change in values of x and y in the formula box.

Point to the Point tools (gray boxes displaying point co-ordinates).


At the bottom of the screen, we have gray boxes to display coordinates of a point.

These gray boxes are called as Point tools.

Drag and place the Point tools on purple and yellow points.

Point to the coordinates.

Drag and place Point tools on purple and yellow points to see the coordinates.
Drag the Point tools Drag the Point tools to the bottom.
Drag the purple point.

Drag one of the Point tool

Drag the purple point to coincide with origin (0, 0).

Drag one of the Point tool and place it on the origin.

Drag yellow point

Point to slope.

Drag yellow point to coincide with (5,5).

Observe that slope of the line is 1.

Click on Save Line button. Click on Save Line button in the formula box.

Line is saved.

Drag the yellow point to (2,8).

Drag the point tool and place it on yellow point.

Drag the yellow point to (2,8).

Drag the point tool and place it on yellow point.

This confirms that yellow point is at(2,8).

Point to Slope Now Slope is 4.
Click on Save Line in right panel. Click on Save Line in the formula box.

Line is saved.

Drag the yellow point to (-5,5).

Drag the point tool.

Drag the yellow point to (-5,5).

Drag and place Point tool on yellow point.

Point to Slope Now Slope is -1.
Click on Save Line in right panel. Click on Save Line in the formula box.

Line is saved.

Drag the yellow point to (-2,8) x=-2, y=8

Point to the slope.

Drag the point tool back to place.

Drag the yellow point to (-2,8).

Point to Slope Here Slope is -4.
Click Save Line. Click on Save Line.

Line is saved

Notice the 6 lines in graph, on left panel. We have drawn 4 lines with different slopes.

Notice that steepness is related to slope.

Slide Number 8

Assignment

As an assignment,

Find when slope is zero and when it is undefined.

Give an explanation.

Cursor on Slope-Intercept screen. Now let us explore Slope-Intercept screen at the bottom of the interface.
Click on Slope-Intercept screen.

Point to the line.

Click on Slope-Intercept screen.

Screen opens with a line y= 2/3x+1.

Point to intercept. Here intercept value is 1.
Point to m and b. In this screen we can change the values of 'm' and 'b'.
Drag the purple point on the line.

Point to the intercept.

Drag the purple point on y axis.

Notice that purple point represents the intercept.

When we move the purple point, intercept for the line changes.

Move the blue point on the line.

Point to the blue point.

The blue point is free to move across the graph.

When we move the blue point, slope of the line changes.

Click on Reset button.
