Interpreting Graphs: Examples of Bar Graphs
This clip explores bar graphs in depth, explaining that each bar represents discrete data. The clip also reminds the student that, "
we'll often have to estimate amounts in bar graphs. Remember, the purpose of a graph is to provide a visual image o...
Interpreting Graphs: Examples of Line Graphs
This clip explores line graphs in depth, explaining that they show data as continuous values. The clip includes examples of line graphs illustrating automobile speed, temperature readings, and semiconductor sales.
Changing Scales of the x and y Axes
When and how to change the scale of an axis.
Coordinate Plane
Graphs are created on an imaginary surface called a coordinate plane, which contains vertical and horizontal number lines. Using the numbers on the axes to plot points on the plane creates a picture of the solution.
Solving Systems by Graphing
Graphing the solution to a system of slope-intercept form equations.
