Finding Intersections on TI-84

Eddie demonstrates how to find the intersection of two lines using a TI-84 calculator. He begins by clearing the calculator's memory, then draws two lines and finds their intersection point. Eddie further explains how to find intersections between a line and a parabola, highlighting the importance of guessing the intersection point. The tutorial concludes with a summary of the steps and a farewell.
