Find the distance between the two points rounding to the nearest tenth (if necessary).
mote1985 [20]

<u>Understanding:</u>

This can be easily solved by using the distance formula which is

d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }\\

d: distance

(x_{1},y_{1}): coordinates of the first point, in our case it is (1,-5)

(x_{2},y_{2}): coordinates of the second point, (4,-1)

<u>Solution:</u>

<u></u>d=\sqrt{[(4)-(1)]^{2}+[(-1)-(-5)]^2}\\=\sqrt{(3)^2+(4)^2}\\=  \sqrt{9+16} \\=\sqrt{25}\\= 5<u></u>

The distance between the two points is 5.
