Find the distance between the two points rounding to the nearest tenth (if necessary).

Sergio [31]

Answer:

6.7 units

Step-by-step explanation:

The distance between two points can be found using the formula below:

$\boxed{{\text{Distance between 2 points}= \sqrt{(y_1 - y_2)^{2} + (x_1 - x_2)^{2} } }}$

Thus, distance between (-1, 2) and (2, -4)

$= \sqrt{( - 4 - 2)^{2} + { [2-(-1) ]}^{2} }$

$= \sqrt{ {( - 6)}^{2} + {(2 + 1)}^{2} }$

$= \sqrt{36 + 9}$

$= \sqrt{45}$

= 6.7 units (nearest tenth)
