The slope of the line can be obtained from the points (-9, 5) and (-17,5)
slope is gven by:
[tex]\begin{gathered} \text{Slope = }\frac{rise}{slope}\text{ =}\frac{y_2-y_1}{x_2-x_1} \\ \end{gathered}[/tex]where x1 = -9 ,y 1= 5
x2 = -17, y2= 5
Substituting this values, we will obtain
[tex]\begin{gathered} \text{slope =}\frac{5\text{ - 5}}{-17\text{ -(-9)}} \\ \\ \text{slope = }\frac{0}{-17\text{ + 9}} \\ \text{slpe = 0} \end{gathered}[/tex]
