Understanding Linear Equations

The video tutorial explains how to find five solutions to the equation y = -0.5x - 2. It demonstrates the process of substituting different x values into the equation to find corresponding y values, resulting in ordered pairs. These pairs are then plotted on a coordinate plane to visualize the solutions, showing that they form a straight line. The tutorial emphasizes the importance of listing solutions as ordered pairs for graphing purposes.

What is the equation we are trying to find solutions for?

• y = -0.5x + 2

• y = 0.5x - 2

• y = -0.5x - 2

• y = 0.5x + 2
