# How do you find the slope for (-5,3) and (12,3)?

Slope=$0$

#### Explanation:

Slope is given by

$\frac{\Delta y}{\Delta x}$

Where Delta ($\Delta$) is the Greek letter that means "change in".

Let's just see how much our $x$ changes by, and how much our $y$ changes by. Recall that coordinates are of the form ($x , y$).

We now know that $\Delta x = 17$ and $\Delta y = 0$.

Plugging into our expression for slope, we get

$\frac{0}{17} = \textcolor{b l u e}{0}$

Thus, our slope is zero. This makes sense, because what we have is a horizontal line, of which the slope is always zero.

Hope this helps!
