Unit test Which graph represents (x, y)-pairs that make the equation y = x - 1 true?
HELP ME PLEASE!

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
