Write an equation of the line through the given points<br><br><br>(0, 4), (3, 3)​
andre [41]

Hello! :)

Step-by-step explanation:

Slope=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}

\frac{3-4}{3-0}=\frac{-1}{3}=-\frac{1}{3}

<u><em>Therefore, the slope is -1/3.</em></u>

<u><em>-1/3 is the final answer.</em></u>

Hope this helps!

Have a nice day! :)
