$30, because basically, it's -100, +100, -30.
Please, when you present a list of numbers, such as 4, 8, 16, ..., separate them with commas or semicolons: 4, 8, 16, ...
If x^2 + y^2 = 16, then 16 represents r^2, and r = 4. r cannot be negative in this type of problem.
It would be 42,523 because 50x10=500 and 5 in 42,523 is in the hundreds spot
I believe it would be -2 since you use rise over run. That would be -2/1
