Top left corner probably depends on what device you’re using
Please ask the question in English, if you are not able to, I believe you are in the wrong language section and suggest you try something else before you get your question taken down.
Slope = change in y / change in x
= (8 - -3) / (1 - 2) = (8 + 3) / ( 1 - 2)
= 11 / -1
= -11
Slope is negative.
