Answer:
-40%
Step-by-step explanation:
NV = new value
OV = old value
percent change = (NV - OV)/(OV) × 100%
percent change = (30 - 50)/(50) × 100%
percent change = -20/50 × 100%
percent change = -40%
The slope is the vertical change per 1 unit of horizontal change so:
v = vert cahnge
h = hor change
slope = v / h
.46 = 1 / h
so solve that equation for h and that's your answer
