£683.10 in New York.

Step-by-step explanation:

Given the following data;

iPhone costs in London = £799

iPhone costs in Paris = €850

iPhone costs in New York = $970

£1 = €1.17 and £1 = $1.42

First of all, to find the cheapest (lowest) price for the three phones we would have to convert the prices to Pounds (£).

a. iPhone costs in London = £799

b. iPhone costs in Paris = €850

To find the price in Pounds (£);

£1 = €1.17

iPhone costs in Paris = €850/€1.17

iPhone costs in Paris = £726.50

c. iPhone costs in New York = $970

To find the price in Pounds (£);

£1 = $1.42

iPhone costs in New York = $970/$1.42

iPhone costs in New York = £683.10

Therefore, the lowest price for the iPhone is £683.10

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
