Recognize details in a word problem that give information about the slope, x-intercept, y-intercept, or other points on the graph of a linear relationship.
The entire walk took 2 hours and the total distance Courtney walked was 8.5 kilometers. Let b be the number of hours it took Courtney to walk from her house to the beach, and p the number of hours it took her to walk from the beach to the park. Which system of equations represents this situation?
In this unit, we learn how to write systems of equations, solve those systems, and interpret what those solutions mean in a real-world contexts. Unit guides are here!
Linear equations and inequalities are the foundation of many advanced math topics, such as functions, systems, matrices, and calculus. Learn how to master them and unlock new possibilities for your future studies and careers in engineering, finance, computer science, and more.
Practice determining which feature of a linear model (the slope, the x-intercept, or the y-intercept) is useful for answering a given question in context.
