Answer:

y=1x-3

Step-by-step explanation:

find the point where the line crosses the y axis, in this case it would be -3. next, find the next point where the line directly crosses a spot on the graph, this would be 3 on the x axis. find how many squares on the graph it took to get there, it would be up 3 and right 3, this would make it 3/3x, or just 1x. your equation is y=1x-3

Nonamiya [84]

Answer:

The answer to your question is: Japan

Step-by-step explanation:

Mobile cost in Spain = € 352.5

Mobile cost in Japan = ¥39856

Exchange rate = £1 = €1.41

£1 = ¥188

Cost of mobile in pounds

£ 1 ------------------ € 1.41

x ----------------- €352.5

x = (352.5 x 1) / 1.41

x= £250

£1 ------------------ ¥188

x ----------------- -¥ 39856

x = (39856 x 1) / 188

x = £212

Then, it was cheaper in Japan
