x is the base and 4 is the exponent
Consider factors of 42, then if the factors can be added or subtracted.
42 = 42 * 1
42 = 21 * 2
42 = 14 * 3
42 = 7 * 6
Since none of these can be added or subtracted to equal 15, no intergers satisfy these criteria.

17: Slope = -5
18: = 1/3
19: = -1/5
20: = Does not exist
21: = 1/4
22: =-2/3
