Understanding Integer Solutions and Graphing a Line

The video tutorial explains how to find integer solutions for the equation y = -2/3x and graph the line. It starts by selecting x values that are multiples of three to ensure integer y values. The tutorial then calculates the corresponding y values for x = 0, 3, and 6, resulting in ordered pairs (0,0), (3,-2), and (6,-4). Finally, it demonstrates how to plot these points on a graph and draw the line representing the equation.

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

• y = -3/2x

• y = 3/2x

• y = -2/3x

• y = 2/3x
