Intercepts and Linear Equations

The video tutorial explains how to graph lines using x- and y-intercepts. It covers multiple examples, including equations like y = 2x + 3, 6(x-1) = 2(y+3), and x + y = 8. The tutorial also includes a practical problem involving a budget for buying strawberries and bananas, demonstrating how to graph the possible combinations of purchases within a $10 budget. The video emphasizes understanding intercepts and connecting points to form lines.

What is the definition of a line in terms of points?

• A line is defined by four points.

• A line is defined by three points.

• A line is defined by two points.
