To write the equation for the trend line of a graph in the form \( y = mx + b \), you will need two key components:
1. **Slope (m)**: This represents the change in y over the change in x. You can calculate the slope by selecting two points on the line and using the formula:
\[
m = \frac{y_2 - y_1}{x_2 - x_1}
\]
2. **Y-intercept (b)**: This is the value of y when x is equal to 0. You can find this directly from the graph where the line crosses the y-axis.
Once you have the values for \( m \) and \( b \), you can plug them into the equation \( y = mx + b \).
If you provide the graph or specific points from the line, I can help you determine the equation for the trend line.
