Considering the graph of a line with a negative slope which of the following could be true?

For this case we have that the generic equation of the line is:
 y = mx + b
 Where,
 m: slope of the line
 b: cutting point with the y axis
 x: independent variable
 y: dependent variable
 When m <0, then as the values of x increase, the values of y decrease.
 Therefore, the line decreases from left to right in the graph.
 
 The line goes down from left to rigth.
 option B

You would have to multiply all of the numbers
