Did you know that the equation represents a straight line on a graph? This line has a slope of 1, which means for every one unit you move to the right along the x-axis, you move one unit up along the y-axis! The y-intercept is 2, indicating that the line crosses the y-axis at the point (0, 2).

When applying this equation in real life, think about budgeting! If you have a fixed amount (like the ‘2’ in our equation) added to your earnings (represented by ‘x’), then your total savings or funds can be modeled by this linear equation. It’s a great visual for understanding how your savings grow as your earnings increase!
