Answer:

The slope of the line is -1.

We can find this by using the slope formula, where
(y_(2) -y_(1) )/(x_(2)-x_(1) ). Substitute in our points;
(7-4)/(6-9) =(3)/(-3). Remember that a negative in either the numerator or the denominator of a fraction makes the entire fraction negative, so
(3)/(-3)=-(3)/(3) Remember that an identical numerator and denominator is equal to 1. Same rule applies here, except it's negative, so the slope of the line is -1. You can see this in action if you were to use a graphing tool. I recommend checking out desmos graphing calculator.
