Evaluating Y-Coordinates from Linear Equations

The video tutorial covers graphing various linear equations, including y = -5x, y = 1/4x, y = 5, x = -6, y = x - 3, y = -7x - 1, and y = -x/3 + 4. The instructor demonstrates how to create tables of values, choose appropriate x-values, and plot points to form lines on a graph. The tutorial emphasizes understanding the properties of horizontal and vertical lines, as well as the impact of fractions and negative slopes on graphing.
