Beth gets on the elevator at the sixth floor. She rides up three floors to meet Doris. They ride down seven floors to meet Julio
Stella [2.4K]

Answer:

4

Step-by-step explanation:

Firstly, she gets on the elevator at the 6th floor. This means she was originally at the 6th floor.

She then stopped in the next three floors. This means she got off at floor 9 where we had Doris.

From Doris, she has to take 7 floors down to meet Julio. This means she went back to floor 2.

Now since her starting position was 6 and she is presently at the 2nd floor, this means she is four floors away from her starting position on the sixth floor.

Is the relationship shown by the data linear? x -9, -5, -1, 3 y -2,-7,-12, -17
Temka [501]
                x               y
            ------           -----
              -9              -2
             -5               -7
             -1              -12
              3               -17

ur x's all have a difference of 4, and ur y's all have a difference of -5...so yes, this is linear with a slope of (-7+2) / (-5 + 9) = -5/4
