Explanation:
The inverse of a slope is the exact opposite slope of the original. I'll show a function below where you can easily solve future problems if you need to.
![- (1)/(m) x](https://img.qammunity.org/2021/formulas/mathematics/college/pp42450sla47xecp0ohn60gkutac1d8v5r.png)
m is the slope, so for the equation above, you simply insert the original slope, being 1, in the equation.
![- (1)/(1) x \\ - 1x](https://img.qammunity.org/2021/formulas/mathematics/college/ygo2dcvv32y9iiigb39dbxluje9ueeik2m.png)
So the inverse slope would be -1.
