Gradient of a graph

[Probability]

Hi, I realise this might not be in the right part of the forum, but please humour me on this one thanks.

I have a linear graph that goes from A to B as shown, I am going to calculate the gradient of the straight line, but am confused as to whether the gradient should be a negative value or positive?

As the straight line goes from the right to the left I thought it should be negative but I could be wrong as always

In the diagram the slope is negative. "Moving" left to right the y-values decrease.

Thank you pka and thanks for the purple maths forum link from your answer "slope" I have also just learned that;

m = y1 - y2 / x1 - x2

is the same as

m = y2 - y1 / x2 - x1
