rosa is at the top of a climbing wall. she descends 48 feet of the wall in 6 equal stages. what number represents the change is Rosa's position at each stage?

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

i believe that the answer is

b. y-1=-2(x-4)

hope this !

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

i believe a. 12x≥120 is the answer
