What expression gives the distance between the points 5,1 and 9,-6

notka56 [123]

<u>Answer:</u>

Distance between the points 5,1 and 9,-6 is 8.0622

<u>Explanation:</u>

Given points = (5,1) and (9,-6)

The square root of this is the distance between the points Distance can be calculated

from the expression= $\sqrt{(x 2-x 1)^{2}+(y 2-y 1)^{2}}$

= $\sqrt{(9-5)^{2}+(-6-1)^{2}}$

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

= $\sqrt{16+49}=\sqrt{65}=8.0622$

Distance (d) from given points = (5,1) and (9,-6) is 8.0622.
