find the slope of these two pairs. (5,1),(11,1)
You'll have better luck on Math section. Anyways: \[slope = \frac{ y2 - y1 }{ x2 - x1 } \to \frac{ 1 - 1 }{ 11 -5 }\] Also if you notice, the y-values of both points are the same. So just by that, you know you have a horizontal line, and you'll have a slope of 0.
