Explanation:

Step1: Identify the distance formula for points with same x - coordinate

For two points $(x_1,y_1)$ and $(x_2,y_2)$ with $x_1 = x_2$, the distance $d=\vert y_1 - y_2\vert$. Here $x_1=x_2=-4.3$, $y_1 = - 9.7$ and $y_2=-1.1$.

Step2: Calculate the absolute - value difference

$d=\vert-9.7-(-1.1)\vert=\vert-9.7 + 1.1\vert=\vert-8.6\vert$.

Step3: Simplify the absolute - value

$\vert-8.6\vert = 8.6$.

Answer:

$8.6$
