Answer:

Option B
$8.54\ units$

Explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^(2)+(x2-x1)^(2)}$

Let

$A(5,7)\\E(-3.4)$

substitute the values

$dAB=\sqrt{(4-7)^(2)+(-3-5)^(2)}$

$dAB=\sqrt{(-3^(2)+(-8)^(2)}$

$dAB=√(73)=8.54\ units$
