## Translate the Line

Draw a short vector somewhere not on Line

*AB*. Use your vector as the translation vector to translate both Line*AB*and its slope triangle.## Question 1

How do the slopes of Line *AB* and Line *A'B'* compare? Why?

## Question 2

Change your translation vector and observe what happens. How would you describe the image of Line *AB* when the translation vector is in the same direction as the line versus when it is not?

## Further Exploration:

1. Change the original line by moving Points

*A*and*B.*Do the relationships you noticed before still hold? 2. Draw a point somewhere not on Line*AB*. Find a translation vector so that the image line goes through the point you draw.
