Jillian walks 0.5 blocks per minute.

#### Work Step by Step

The number of blocks per minute Jillian walks is also the slope of the graph. Plot two points $(2,4)$ and $(4,3)$ Use the slope formula: $m=\frac{y_2-y_1}{x_2-x_1}=\frac{3-4}{4-2}=-\frac{1}{2}$ Therefore, Jillian walks 0.5 blocks per minute.
