6. Continue counting up and over to each point.
What relationship do you notice between the points?
up 1 and over 2 between each pair of points

7. The ratios are the same when they are in simplest form.
Start with the point on the farthest left and go to the farthest point on the right. What do you notice about the ratio when you compare it with the original ratio?
over 8
up 4
The ratios are the same when they are in simplest form.
