Answer:
6.4 units (nearest tenth)
Step-by-step explanation:
Distance between 2 points
[tex] = \sqrt{(y1 - y2)^{2} + (x1 - x2)^{2} } [/tex]
Distance between A and B
[tex] = \sqrt{[ - 1 - ( - 5)]^{2} + ( - 1 - 4)^{2} } [/tex]
[tex] = \sqrt{( - 1 + 5)^{2} + ( - 1 - 4) {}^{2} } [/tex]
[tex] = \sqrt{ {4}^{2} + ( - 5) {}^{2} } [/tex]
[tex] = \sqrt{41} [/tex]
= 6.4 units (nearest tenth)
