The video tutorial covers Math 8 Unit 4 Lesson 12 on systems of equations. It begins with an introduction to the concept, followed by practical problems involving milkshakes, hiking, and stacks of cups to illustrate the application of systems of equations. The tutorial also discusses graphing these systems, focusing on slopes, intercepts, and intersection points. It concludes with an exploration of different types of solutions, including no solution, one solution, and infinitely many solutions.

How far is Jada from the parking lot when Han starts his return?

• 4 miles

• 7 miles

• 5 miles

• 6 miles

What is Han's speed on the hiking trail?

• 3.2 mph

• 2.4 mph

• 5.6 mph
