In the image, we are given a geometric reflection of a shape across a line, with dotted lines representing the path between points on the original shape and their reflections. The two questions ask for:

1. The slope of one of the dotted lines.
2. The slope of the line of reflection.

Step 1: Slope of one of the dotted lines

To find the slope of one of the dotted lines:

• Select two points from one dotted line.
• Use the slope formula:

$\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}$

Step 2: Slope of the line of reflection

The line of reflection is shown as a solid line intersecting the origin and slanting through the quadrants. To determine its slope:

• Pick two points on the line of reflection (preferably grid points like $(0, 0)$ and another visible point).
• Use the same slope formula as above.

Would you like me to assist with calculating these slopes in detail from the image?

Relative questions:

1. How do you calculate the slope of a line given two points?
2. What happens when you reflect a shape across a line with a slope of 1 or -1?
3. How does changing the slope of the reflection line affect the image?
4. Can you predict how the coordinates of points change after reflection?
5. What are the key differences between rotation and reflection transformations?

Tip: The slope of the reflection line determines the angle at which the original shape is reflected.
