Option B

Budget  858€

Step-by-step explanation:

City   -  Cost (€)

Berlin 171

Wiesbaden 263

Hanover 169

Dresden 215

Kiel 209

Stuttgart 297

Potsdam 179

Munich 159

Cost of original plan

Stuttgart + Dresden + Weisbaden + Berlin  =

297€ + 215€ + 263€ + 171€  = 946 €

Lets evaluate the options to see which one can get the budget under 860€

a) Replace Dresden with Potsdam

Postdam - 179€

297€ +(179)€ + 263€ + 171€  = 910€

Not the correct choice

b) Replace Stuttgart with Kiel.

Kiel 209€

(209)€ + 215€ + 263€ + 171€  = 858€

Correct choice

The slope of the line is negative because the line when left to right goes from top to bottom. If goes from bottom to top then it is positive.
