Hello there!
Use the slope formula:
m=![\frac{y2-y1}{x2-x1}](/tpl/images/2538/0365/71a0a.png)
Now, plug in all the values:
The slope is 0. Why?
If we are given 2 points and their y-coordinates are the same, then the line is a horizontal line. Its rise is zero.
Another formula for Slope is Rise/Run. If the rise (the amount of units we move up) is 0, then the slope is 0.
Therefore, the slope is 0.Hope this helps you!
