Equation:

This equation describes a straight line in slope-intercept form, where the slope is and the y-intercept is . This means for every 8 units you move to the right along the x-axis, you move up 3 units along the y-axis. If you were to graph it, you’d start at the point on the y-axis and use the slope to find other points on the line.

In real-world scenarios, this linear equation might represent a relationship between two variables—like distance and fuel consumption or cost and quantity. Imagine you’re budgeting your expenses: if your company charges a flat fee of 3 (the starting point), and then adds a smaller incremental charge that scales with usage (represented by ), you could predict costs based on usage!
