# How do you sketch the graph of y=sin (pi)x ?

The graph will look like this:

#### Explanation:

It is actually a simple problem.
Since $x$ is being multiplied by $\sin \pi$, we will have a straight line.

So let's see what $\sin \pi$ is.
You can use your unit circle definition to find out that $\sin \pi = 0$.

This means that for any given value of $x$, $y = 0$. Therefore, we have a line with a slope of $0$ that goes across the x-axis.
