Understanding Integer Solutions and Graphing

The video tutorial explains how to find integer solutions for the equation 3x - y = -1. It demonstrates solving the equation for different x-values (0, 1, and 2) to find corresponding y-values, resulting in ordered pairs. These pairs are then plotted on a graph to sketch the line representing the equation. The tutorial emphasizes that each solution is a point on the graph and provides a step-by-step guide to solving and graphing the equation.

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

• 3x - y = -1

• x - 3y = 1

• 2x - y = -3

• 2x + y = 1

What is the significance of the points (0, 1), (1, 4), and (2, 7) on the graph?

• They are random points.

• They do not lie on the line.

• They are solutions to a different equation.
