Answer 1

\(\bf slope = m= \cfrac{rise}{run} \implies \cfrac{y_2-y_1}{x_2-x_1}\\ \quad \\
\textit{what is the slope of a "horizontal line"?}\\
\textit{notice the "rise", the }y_2-y_1 =0\textit{ so the slope is 0}\\ \quad \\
\textit{the derivative }\cfrac{ds}{dt}\textit{ gives the equation for the slope}\\
\textit{set }\cfrac{ds}{dt}=0 \textit{ and solve for }v_o\)
