Study Notes
Introduction to Graph Terminology
- A graph consists of perpendicularly intersecting lines called axes.
- The range of the scale on a graph represents all the numbers from where the perpendicular lines intersect to the edge of the graph.
- The scale of the graph represents the value of each tic mark present on the graph.
Understanding the Axis on a Graph
- A graph is made up of a coordinate grid, also known as an axis graph.
- The axis graph shows the intersection of two real number lines: one horizontal (X-axis) and one vertical (Y-axis).
- The X-axis is the independent variable of the data set, while the Y-axis is the dependent variable of the same data set.
- A point on a graph is listed as an ordered pair (X, Y).
Graph Line Names: X and Y Axes
- The X-axis is the horizontal line, representing the independent variable.
- The Y-axis is the vertical line, representing the dependent variable.
- The X and Y axes are normally defined as ordered pairs in data sets, denoted as (X, Y).
The X-Axis on a Graph
- The X-axis is the horizontal line, representing the FIRST number in an ordered pair (X, Y) for a data point on a graph.
- The X-axis runs left-to-right, or horizontal.
The Y-Axis on a Graph
- The Y-axis is the vertical line, representing the SECOND number in an ordered pair (X, Y) for a data point on a graph.
- The Y-axis runs up-and-down.
X, Y-Axis Chart
- Graphs can be either linear (showing changes in data that create a straight line) or polynomial (showing changes that vary).
- Linear axis charts show that a change in X produces the same change in Y.
- Polynomial axis charts show that a change in X does NOT produce an equal value of Y.
Which Axis Goes First?
- When plotting an ordered pair, the value of X goes first, and the value of Y is second.
- To create a data point, take the value of X, move horizontally to that number, then move vertically to the value of Y to plot the data point.
Exploring the Range of a Graph
- The range of a graph is found by moving vertically to find the difference between the highest and lowest values of Y.
- The range is the difference between the highest and lowest values for data in the direction of the Y-axis.
How to Find the Range on a Graph
- Find the lowest and highest values on the Y-axis.
- Subtract the smallest number from the largest number to find the range.
What is the Domain of a Graph?
- The domain of data is the difference between the highest and lowest values for data on the X-axis.
- The domain is found by subtracting the lowest number on the X-axis from the highest number on the X-axis.
