The answer is "The water bill increases by about $19 for every additional resident in the home" which represented by the slope of the equation. The equation above consists of y as the dependent variable, x as the independent variable, 19.485 as the slope, and 86.912 as the constant. The constant represent the fixed water bill. The x variable represents the additional water usage.
