Answer
Slope of the line is $\frac{5}{2}$.
Work Step by Step
Take first two points from the table.
$(x_1,y_1)=(2,10)$ and $(x_2,y_2)=(4,15)$.
Use slope formula.
$m=\frac{y_2-y_1}{x_2-x_1}$
Substitute all the values.
$m=\frac{15-10}{4-2}$
Simplify.
$m=\frac{5}{2}$
Hence, the slope of the line is $\frac{5}{2}$.
