solving a linear system of two equations by graphing

The video tutorial explains how to graph a linear system of equations by first graphing each equation separately and then plotting them on the same coordinate axis. It covers the concepts of slope and y-intercept, and demonstrates how to find the intersection point, which represents the solution to the system. The tutorial emphasizes the importance of understanding each equation individually before combining them to solve the system.

Explain the significance of the y-intercept in graphing linear equations.

What does it mean when two linear equations intersect on a graph?
