How do you find the slope of (7, 0) and (0, -5)?

I found: Slope$= \frac{5}{7}$
The slope of a line joining two points of coordinates $\left({x}_{1} , {y}_{1}\right)$ and $\left({x}_{2} , {y}_{2}\right)$ is given as:
Slope$= \frac{\Delta y}{\Delta x} = \frac{{y}_{2} - {y}_{1}}{{x}_{2} - {x}_{1}}$
Slope$= \frac{- 5 - 0}{0 - 7} = \frac{5}{7}$
