Group Activity: Graph of a Linear Equation
In this Activity, you are going to learn about the trend/behavior of the graph by dragging the slider tool to investigate its effect to the graph of linear equation y=mx + b.
Objectives:
At the end of this activity, you will be able to describe the graph of a linear equations in terms of its intercepts and slope.
Questions for Discussion:
1.) Drag the slope slider from left to right and vice versa. What happens to the graph?
2.) What is the trend/behavior of the graph when its slope (m) is:
a.) positive?
b.) negative?
c.) zero?
3.) Drag the slope(m) slider and y-intercept(b) slider from left to right and vice versa. What did you observe to the graph?
4.) What happens to the graph when the value of slope and y-intercept (b) increases? decreases? become zero?
5.) What can you say about the x-and intercept when the slope is positive? negative? zero?
6.) Based on your observation as you move the slope(m) slider, which graph of a linear equation is steeper?
