Graphing Linear Equations: Key Concepts and Techniques

Mr. Cosy presents a lesson on graphing linear equations, starting with the basics of creating a good graph using graph paper and straight edges. He explains what linear equations are and how to graph them using a T-table method. The lesson includes a practice problem and discusses horizontal and vertical lines. The video concludes with a review of the key points and encourages practice.

What materials are recommended for graphing linear equations?

• Colored pencils and plain paper

• Pencil, straight edge, and graph paper

• Digital tools only

• Marker and whiteboard

Why is it important to use graph paper for plotting graphs?

• It provides color

• It ensures accuracy and neatness

• It is cheaper

• It is more durable

What is the maximum power of the variable in a linear equation?

• Zero

• Two

• Three

• One

How many points are recommended to plot to ensure a correct line graph?

• Four

• One

• Two

• Three

What is the first step in graphing the equation Y = 2x + 3?

• Label the axes

• Set up a T-table

• Draw the line

• Plot the points

How do you rearrange x - 4 = -2y to make y the subject?

• Subtract x from both sides

• Multiply all terms by -2

• Add 2y to both sides

• Divide all terms by -2

What type of line does the equation y = 4 represent?

• Vertical line

• Horizontal line

• Diagonal line

• Curved line

What does the equation x = -2 graphically represent?

• A curve passing through -2

• A vertical line at x = -2

• A horizontal line at x = -2

• A diagonal line through -2

What should you do after learning how to graph linear equations?

• Move to advanced topics

• Teach others immediately

• Practice more

• Forget about it
