Graphing Rational Points on Coordinate Plane

This video tutorial explains how to graph rational numbers on a coordinate plane. It covers common mistakes in plotting points, such as incorrect order of plotting and misunderstanding fractional and decimal values. The tutorial demonstrates plotting positive and negative rational numbers, as well as decimal numbers, using different scales on the coordinate plane. It emphasizes the importance of estimation when dealing with non-integer values and concludes with a summary of the key points covered.

In which quadrant would the point (1/2, 2) be located?

• Quadrant III

• Quadrant II

• Quadrant I

• Quadrant IV

How do you plot the point (-1, 1/4) on the coordinate plane?

• Go left 1 and down 1/4

• Go left 1 and up 1/4

• Go right 1 and down 1/4

• Go right 1 and up 1/4

What is the correct way to plot decimal numbers on a coordinate plane?

• Ignore the decimal part

• Estimate their position based on the scale

• Plot them as whole numbers

• Convert them to fractions first

When the scale changes, what is a key consideration for plotting points?

• Use a ruler for accuracy

• Estimate the position of points

• Ignore the scale change

• Plot only whole numbers

• By connecting two points

Why might some points appear in the center of squares on a coordinate plane?

• To avoid overlapping lines

• To make the graph look better

• Because they are incorrect

• Due to estimation when plotting
