Answer 1

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, as the graph or points of each city are not given.

So, I will provide a general explanation.

To calculate the equation of line through two points;

Start by writing out the coordinates of the two points.

For instance:

$London = (4,6)$

$Warsaw = (20,10)$

This points will be represented as:

$(x_1,y_1) = (4,6)$

$(x_2,y_2) = (20,10)$

Calculate the slope (m)

$m = \frac{y_2 - y_1}{x_2 -x_1}$

$m = \frac{10 - 6}{20 - 4}$

$m = \frac{4}{16}$

Simplify

$m = \frac{1}{4}$

The equation is then calculated as:

$y = m(x - x_1) + y_1$

This gives:

$y = \frac{1}{4}(x - 4) + 6$

Open bracket

$y = \frac{1}{4}x - 1 + 6$

$y = \frac{1}{4}x +5$

Apply the above steps in the original question
