56.38,51.28,46.18,41.08 what is the rule

The rule is 5.10 because 56.38 to 51.28 is ~ 56 - 51 = 5 then 38 - 28 = 10. If you carry on doing the same thing, you will figure out the pattern. Overall the answer is 5.10.

I hope this helps! :)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Ibelieve the answer is b. y=0 would make the line horizontal across the x.
