Answer:

6.4 units (nearest tenth)

Step-by-step explanation:

Distance between 2 points

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

Distance between A and B

=  \sqrt{[ - 1 - ( - 5)]^{2} + ( - 1 - 4)^{2}  }

=  \sqrt{( - 1 + 5)^{2} + ( - 1 - 4) {}^{2}  }

=  \sqrt{ {4}^{2} + ( - 5) {}^{2}  }

=  \sqrt{41}

= 6.4 units (nearest tenth)
