The slope between two points (x1,y1) and (x2,y2) is given by:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]In this case we have the points (1990,2201900) and (1994,2202100), hence we have:
[tex]\begin{gathered} m=\frac{2202100-2201900}{1994-1990} \\ m=\frac{200}{4} \\ m=50 \end{gathered}[/tex]Therefore the slope is 50.
