Answer:
0 or no slope
Explanation:
Slope formula:
m = y₂ - y₁ / x₂ - x₁
Two points are given:
(5, 9) (−2, 9)
m = 9 - 9 / -2 - 5
m = 0 / -7
m =
![(rise)/(run)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/d04q2ryncfcbrti36x4yn7d4say9uljm9h.png)
As you can see here and at the result, there is zero rise, so at this point the slope of the line joining (5, 9) and (−2, 9) is zero or no slope
