Line plots

# Making picture graphs and line plots

To create a line plot, ​first create a number line that includes all the values in the data set. Next, place an X (or dot) above each data value on the number line. If a value occurs more than once in a data set, place an Xs over that number for each time it occurs.

• why do we use picture graphs?
• I think we use picture graphs to make the understanding better. It is a great way to visualize the math problem and be able to answer it much more easier
• Where can we apply these line plots??
• In the animation fields, architecture and also in higher grades....
• why do we use picture graphs
• So we can get "used to" or make it easier for us to see the graph, and trust me when you get into higher math it gets harder without picture graphs...
• What is a graph
• it is not garagh is graph
Graph is something which we counght on it
• I learned about picture graphs but not line plots and also do we actually use line plots or do we just use them in khan academy?
• You will encounter them at various stages as you move along through different math classes. Certainly used places other than Khan Academy.
• whats a number line
• Good question! A number line is usually a horizontal line used for visualizing the relationships between numbers, including whole numbers, integers, decimals, fractions, and irrational numbers (for example pi, square root of 2, etc). Larger numbers are placed to the right of smaller numbers. Numbers to the right of 0 are positive, numbers to the left of 0 are negative, and 0 is neither positive nor negative.

Sometimes a number line is vertical. Then greater numbers are placed above smaller numbers.

Number lines are often used in algebra and for displaying data (for example dot plots and histograms). When you study graphing points and equations on a coordinate grid, you will see two number lines: a horizontal line called the x-axis, and a vertical line called the y-axis. Coordinate grids are also used to create scatterplots that display two-variable data.

Have a blessed, wonderful day!
• are line plots a tipe of number line 'cause it kinda looks like it
• Yeah, you use a number line as a base for a line plot. In the future you will learn that there are other ways to use a number line.
• could you use somthing else besides dots on a line plot
