x 0 1 2 3 y 3 5.5 8 10.5

Given:
The objective is to find the slope of the given coordinates.
Consider any two coordinates.
[tex]\begin{gathered} (x_1,y_1)=(0,3) \\ (x_2,y_2)=(1,5.5) \end{gathered}[/tex]The formula to find the slope is,
[tex]\begin{gathered} m=\frac{\Delta y}{\Delta x} \\ m=\frac{y_2-y_1}{x_2-x_1} \end{gathered}[/tex]Now, substitute the given coordinates in the formula of slope.
[tex]\begin{gathered} m=\frac{5.5-3}{1-0} \\ m=\frac{2.5}{1} \\ m=2.5 \end{gathered}[/tex]Hence, the slope of the given table is 2.5.
