To write the equation of a trend line in slope-intercept form (y = mx + b), we need to identify the slope (m) and y-intercept (b) from the trend line shown in the image. Since I don't have access to the image, I cannot provide the specific equation. However, I can guide you on how to determine the correct equation:

  1. Identify two points on the trend line. For example, if the trend line passes through points (x1, y1) and (x2, y2).
  2. Calculate the slope (m): Use the formula: \[ m = \frac{y2 - y1}{x2 - x1} \]
  3. Find the y-intercept (b): Plug one of the points into the slope-intercept form of the equation to solve for b.
  4. Construct the equation: Once you have m and b, plug them into the slope-intercept form.

If you can provide coordinates or specific information from the image, I can help you derive the precise equation. Otherwise, based solely on the options you've given, you would need to compare these with your calculated slope and y-intercept to find the correct match.
