What is a graphical linear function?
A linear function that is displayed on a graph or a graphical device. Where the function's different values for n variables can be iterated or cross-referenced with other functions.
What does doubled-graph mean?
You use 2 colors for the bars so you can compare things. Maybe one color for male unemployment, and one color for female over several years. You can look to se trends for increasing and decreasing unemployment and you can see which consistently has a higher unemployment or if one sex had higher unemployment then maybe it switched to the other.
Which type of graph would best represent the differences in size between two variables?
A scatter graph with one variable plotted along the x-axis and the other along the other axis.
What can a line graph tell you the relationship between the variables in an experiment?
A line graph can tell you how changes in one variable are related to changes in the other. A line graph cannot show causality. A line graph can show non-linear relationships which some other analytical techniques may not identify. In particular, they are good for identifying relationships between the variables that change over the domain. A line graph can also help identify points where the nature of the relationship changes - eg tension and breaking point, or temperature and phase. The spread of observations about the "line of best fit" gives a measure of how closely the variables are related and how much of the measurement is systemic or random error.
When looking for a mathematical relationship between two variables use?
line graph or a scatter plot.
What graph best shows how different items compare to each other?
a bar graph
What is best shown on a bar graph?
How different items compare to each other
What does a bar graph look like?
A bar graph is a graph that has vertical or horizontal bars to represent numbers. A bar graph is usually used to compare two different things with each other.
How can you find coordinates on a line graph?
Select any value for one of the variables in the graph and solve the equation to get the other variable.
A graph that uses sectors of a circle to compare parts to the whole and parts to other parts?
it is a circle graph
What is a graphical linear function?
A linear function that is displayed on a graph or a graphical device. Where the function's different values for n variables can be iterated or cross-referenced with other functions.
Would let you show a relationship between two variables where each piece of data is represented independently of any other data?
Bar Graph
How do various gps handheld devices compare with each other?
There are many different functions and features which differentiate the various models of GPS devices. You should compare the devices based on variables such as price, size, wifi capability, bluetooth capability, and other features.

You can look to se trends for increasing and decreasing unemployment and you can see which consistently has a higher unemployment or if one sex had higher unemployment then maybe it switched to the other.
When would you use a line graph and not a bar graph?
In two main situations: 1. When there are so many observations that the bars would be extremely thin, and also differences in class widths are no longer of great importance. 2. When you wish to compare two (or more) "dependent" variables, and if plotted as bars, one would hide the other.
What are the two way to determine if the relationship between two quantities are proportional?
Graphical: If two variables are proportional, the graph of one of the variables against the other is a straight line through the origin.Algebraic: If the ratio of the two variables is a constant.
Which type of graph would best represent the differences in size between two variables?
A scatter graph with one variable plotted along the x-axis and the other along the other axis.
