What happens when the slope of the line is negative?

The graph of the line goes down as we move to the right

Step-by-step explanation:

Since the slope is negative, that means the quotient "rise/run" is a negative value.

As we move to the right (with a positive increment for the "run"), the rise must be negative to give a negative value to the quotient if those two numbers,

A "negative" rise implies that instead of an actual "rise" of the line, we observe a DROP which leads to smaller values in the vertical axis.

The line will go go and to the left
