In the following tutorial, students will learn about the law of conservation of energy. They will read about some of the many forms of energy. They will understand the definition of efficiency of an energy conversion process as the...

Slope-intercept form of a line is shown in formulas and examples with this Purplemath lesson. There are examples of slope-intercept with the slope and a point and with two points. Includes interactive widgets for exploring concepts.

Given real-life problems, the student will select an appropriate method and solve problems involving proportional relationships.

The interactive resource investigates slope and intercept. Students adjust the sliders to control the slope (m) and the intercept (b) of the line. The equation and the line will change accordingly. Learners can also drag the origin.

Given algebraic, tabular, or graphical representations of linear functions, the student will determine the intercepts of the graphs and the zeros of the function.

This tutorial looks at the anatomy of the eye and how the sense of sight works. This is the first part of a learning module. Subsequent sections cover how images are formed and detected, the concept of accommodation where the eye adjusts...
