1. The problem asks to find the slope of the line shown on the graph. 2. The slope of a line is defined as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line. It is given by the formula: $$\text{slope} = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}$$ 3. Important rules: - A positive slope means the line rises from left to right. - A negative slope means the line falls from left to right. - A slope of zero means the line is horizontal. - An undefined slope means the line is vertical. 4. From the description, the top-left graph has a line with a positive slope approximately $\frac{3}{7}$. 5. Therefore, the slope of the line in the top-left graph is: $$\boxed{\frac{3}{7}}$$ This is the slope value to use for the first step in the maze.
