Arrange the following points with the steepest slope at the top down to the least steep slope.

1. (0,-1) and (2,3)
2. (1,3) and(5,5)
3. (0,0) and (3,3)
4. (-6,1) and (4,8)

The arrangement of the points from steepest slope to least steep slope is as follows:

1. (-6,1) and (4,8) - This line has the steepest slope, as it goes from a lower point to a higher point.

2. (0,0) and (3,3) - This line has a slope of 1, which is less steep than the first line but steeper than the remaining lines.

3. (1,3) and (5,5) - This line has a slope less than 1, making it less steep than the first two lines.

4. (0,-1) and (2,3)- This line has the least steep slope among the given options, as it has a small change in y relative to the change in x.
