If you were at 54 on the number line you would have to cross zero and go an extra 13 steps to get to -13.
So we want the difference between 54 and -13 or 54- -13 which becomes 54+13 which is 67 - that is the range
Y = -2x+0
I don't think you need to add the 0 though.
Radius is half of the diameter so the radius of 4 is 2
Answer:

Step-by-step explanation:
