One characteristic of all linear functions is that they change by? 1.)equal factors over equal intervals 2.)unequal factors over equal intervals 3.)equal differences over equal intervals 4.) unequal differences over equal intervals

Equal differences over equal intervals, because a linear function is a function whose value is being incremented by the same value over and over. 2. Is also a technically correct but non-useful property of a linear function.

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)
