multiple - choice question
2 units
4 units
8 units
rewatch

Explanation:

Step1: Identify x - coordinates

Let $(x_1,y_1)=(6, - 3)$ and $(x_2,y_2)=(-2,1)$. For horizontal leg, focus on x - values.

Step2: Calculate horizontal distance

$d_x=\vert x_2 - x_1\vert=\vert-2 - 6\vert=\vert-8\vert = 8$

Answer:

8 units
