Ron has several solar panels on the roof of his garage and plans to add more solar panels to the roof of his house. The total amount of energy his solar panels will produce on a sunny day depends on how many new solar panels Ron adds.
This situation can be modeled as a linear relationship.
What does the y-intercept of the line tell you about the situation?

The y-intercept of the line represents the amount of energy produced by the existing solar panels on Ron's garage when there are no additional solar panels added to the roof of his house. In other words, it represents the baseline amount of energy that Ron's solar panels produce on a sunny day without any further additions.
