Modeling with Linear Equations Example 2

Practice graphing basic equations. Algebra learners complete a table showing values of x and y. They graph the results on a coordinate grid. There are six problems: three equations are linear, and three are quadratic. The "show your...

In this video, Sal solves a word problem sent in by a listener with two cyclists riding towards each other over a given time. It is an interesting problem regarding ratios and the relationship between distance, rate, and time. He shows...

Sal starts to solve a trigonometric word problem of a wayward ship captain who veers off course and once aware of his predicament, needs to know how far he is from his destination. Instead of using the Law of Cosines in his solution, Sal...

Concepts from the last few videos, particularly exponential growth and decay functions, are covered in this video about word problems. Viewers can apply their new (or growing) algebraic knowledge to solve the word problems along with Sal.

One of the beauties of mathematics is the ability to take words and turn them into symbols. The lesson uses a graph to tell a story, and translates a description of water changing temperatures into a graph. The instructor then reviews...

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to more complex word problems.

For this linear word problems worksheet, students solve fifteen different word problems that are related to linear equations. First, they solve various multi-step problems in one variable. Then, students solve and provide justification...

Yes, it's a word problem but you have all the information you need to solve it. You have a formula, and they have given you a value to plug in. So get to it and write out the formula, plug in the value and solve this word problem.

The instructor illustrates an approximate graph to plot the terms of this word problem. There are several parts on this graph that need to be identified before plotting. The instructor does a good job explaining the word problem as she...
