Answer:

13.3 units (nearest tenth)

Explanation:


\boxed{Distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^(2) + {(y1 - y2)}^(2) } }

Using the formula above, distance


= \sqrt{ {[2 - ( - 1)]}^(2) + ( - 9 - 4)^(2) }


= \sqrt{ {(2 + 1)}^(2) + ( - 13) {}^(2) }


= \sqrt{ {3}^(2) + ( - 13) {}^(2) }


= √(9 + 169)


= √(178)

= 13.3 units (nearest tenth)
