Lecture notes for Section 2.1
... When we want to visually summarize all the possible answers to an equation, we graph the equation. The easiest way to do this is to calculate a few points by hand, and then plot those points on a graph. Usually, it is easy enough to “connect the dots” to fill in the rest of the graph. One thing to r ...

Section 1.2 Graphs and Lines
... where t is the number of years since the dam was constructed, and w is measured in feet. (a) Sketch a graph of this equation. (b) What do the slope and w-intercept of this graph represent? Solution: (a) This equation is linear, so its graph is a line. Since two points determine a line, we plot two p ...

Chapter 5 – Simplifying Formulas and Solving Equations
... A linear equation is an equation where the variable is to the first power. If a variable has an exponent of 2 (square) or 3 (cube) or higher, then it will require more advanced methods to solve the problem. In this chapter we are focusing on solving linear equations, but first we need to talk about ...
