Graphing the Equation F = 1.8C 32
Graphing the equation F = 1.8C 32 to convert temperatures given in Celsius to Fahrenheit.
Effect of Scale on Slope
The effect of scale on the steepness of a line's slope is illustrating by comparing graphs of interest rates at two different banks.
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.
