Graphing a linear equation from a table

The video tutorial explains how to graph linear equations using a table. It begins with setting up the XY axis and plotting coordinate points. The instructor demonstrates how to plot points such as (-2, 2) and (0, -4) on the graph. The tutorial then shows how to connect these points to form a straight line, emphasizing that the line extends indefinitely. The video concludes by identifying the Y intercept at (0, -4) and estimating the X intercept between -2 and -1.

What is the purpose of setting up an XY axis when graphing linear equations?

• To calculate the area under the curve

• To determine the slope of the line

• To coordinate points with X and Y values

• To identify the intercepts

When plotting the point (-2, 2), which direction do you move on the X and Y axes?

• Right 2 units, up 2 units

• Right 2 units, down 2 units

• Left 2 units, down 2 units

• Left 2 units, up 2 units

How do you plot the point (0, -4) on the graph?

• Stay on the X axis and move down 4 units on the Y axis

• Move left 4 units on the X axis

• Stay on the X axis and move up 4 units on the Y axis

• Move right 4 units on the X axis

What happens when you connect the plotted points on a graph of a linear equation?

• You form a curved line

• You form a circular shape

• You form a straight line

• You form a zigzag pattern

Where is the Y intercept located in this graphing example?

• At (2, 0)

• At (-2, 0)

• At (0, -4)

• At (0, 4)
