Graphing Points and Scales

The video tutorial focuses on graphing points and selecting appropriate scales for the axes. Haley is graphing the points (3, 32), (5, 39), and (2, 27). The origin is set at (0, 0), and the video discusses why a scale of 0 to 10 is suitable for the X-axis, given the small and positive values of the X-coordinates. For the Y-axis, a scale of 0 to 50 is chosen as it fits the range of the Y-coordinates, which are all less than 50 and greater than zero. The video concludes that these scales are the best choices for accurately representing the data points on the graph.

What is the most logical choice for the origin when graphing points?

• (5,5)

• (1,1)

• (10,10)

• (0,0)

Why is a large scale like 0 to 100 not suitable for the x-axis in this scenario?

• The x-values are zero.

• The x-values are too small.

• The x-values are negative.

• The x-values are too large.

Which of the following x-axis scales would be most appropriate for the points given?

• 0 to 200

• 0 to 10

• 0 to 50

• 0 to 100

What is the range of y-values for the points being graphed?

• 0 to 50

• 0 to 200

• 0 to 10

• 0 to 100

Why is a y-axis scale of 0 to 50 appropriate for the given points?

• All y-values are zero.

• All y-values are between 0 and 50.

• All y-values are negative.

• All y-values are above 50.

What is the final choice for the scales on the graph?

• X: 0 to 10, Y: 0 to 50

• X: 0 to 50, Y: 0 to 100

• X: 0 to 100, Y: 0 to 200

• X: 0 to 200, Y: 0 to 500
