Find the distance between the two points rounding to the nearest tenth (if
Olin [163]

Answer:

d=9.2

Step-by-step explanation:

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

d=\sqrt{(1-8)^2+(1-(-5))^2}

d=\sqrt{(-7)^2+(1+5)^2}

d=\sqrt{49+(6)^2}

d=\sqrt{49+36}

d=\sqrt{85}

d=9.21954

d=9.2
