# How do you find the slope of y=4/5?

Jul 18, 2016

This function is constant, so $\text{slope} = 0$.

#### Explanation:

graph{0x +4/5 [-10, 10, -5, 5]}

As we can see on the graph, $y$ is always the same. It happens because there isn't a $x$ present in the function $y = \frac{4}{5}$.

Now you may think that it is true, but it isn't. $x$ actually is present, but it remains hidden beucase $x \cdot 0$ or any number multiplied by 0 equals 0.

So, when you see any function that $x$ is not visually appearing, remember that it is there, but its $\text{slope} = 0$.

Hope you understand!
