You could write 42/20 for #60.
From least to greatest: |6.99|,|-7.09|,|7.15|,|-7.18|,|-7.21|. This is becauase every value will be positive because of the absolute value
We analyze the linear function to find that it has equation

. Drawing the line, we find that it
will intersect the circle at negative and positive x-coordinates.We can prove this by
substituting 
into the given equation:




Hence,

or

, so there are both positive and negative values for

.
The formula to find the slope of a line is

.
I'm not sure if my fraction looks right, so I'll add it in a separate attachment too.
