Functions can be represented by graphs. When graphed, linear functions become straight lines, with their direction and position determined by the slope and y-intercept.

While equations and functions are different, by drawing graphs of functions corresponding to equations, we can visually understand the characteristics and solutions of equations.

This article explains the basics of plane geometry for 8th-grade students. Learn about the relationship between angles and parallel lines, and understand the concepts of vertical angles, corresponding angles, and alternate angles. Use interactive diagrams to visually learn and confirm the properties and conditions of parallel lines. This content provides important foundational knowledge for solving geometric problems.

What are quadratic equations

Let's look at how to solve quadratic equations. In addition to the properties of equations, knowledge of square roots and factorization is necessary because it's a quadratic expression.
