There are two types of lectures in this site—those that I wrote for my Math 154 Elementary Online class and those I wrote specifically for Math 152. The lectures written for Math 154 are marked using (Math 154).
Linear Equations
- Solving a linear equation that contains fractions. (Math 154)
- Graph a linear equation using intercepts. (Math 154)
- What is “slope”? (Math 154)
- Graphing linear equations using the slope and y-intercept. (Math 154)
- Graphing Vertical and Horizontal Lines (Math 154)
- Given the graph of a line, find the equation of the line. (Math 154)
- Find the linear equation in slope-intercept form when you are given the slope and a point. (Math 154) Used the point-slope form of equation to do this. There are other methods.
- Find the linear equation when you are given two points. (Math 154) Used the point-slope form of equation to do this. There are other methods.
- Find the equation of a line going through a point and parallel to a given line.
- Find the equation of a line going through a point and perpendicular to a given line.
