i will give brainlist if you give explantion of how to do it and give a answer

Answer 1

Hello!

To solve this question, you have to look at this question as if they were from a graph.

You see the little point where the square is?
That will be the origin of the graph.

$In\ mathematics\ \boxed{ m= { \frac{y_1 - y_2}{x_1 - x_2} } } \\ Where\ m = slope\ of\ the\ graph$

The 2 given coordinates are (0, 2.5) and (10, 0)

Substitude them in the formular.

$m= { \frac{2.5 - 0}{0 - 10} } \\ m= { \frac{2.5}{-10} } \\ m= - { \frac{1}{4} }$
