Question

Find the distance between the points. (1, 5), (-7, -2)

Answer 1

Answer:

Distance = $\sqrt{113}$

Step-by-step explanation:

$(1, 5) = (x_1,y_1)\\ (-7, -2)=(x_2,y_2)\\\\d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\ \\d = \sqrt{(-7-1)^2+(-2-5)^2}\\ \\d = \sqrt{(-8)^2+(-7)^2}\\ \\d = \sqrt{64+49}\\ \\d = \sqrt{113}$

Answer 2

Answer:$\sqrt{113}$

Step-by-step explanation:

Distance formula: $\sqrt{(x2-x1)^2+(y2-y1)^2}$

x1=1     x2=-7     y1=5     y2=-2

----------------------------------------------------------------

 $\sqrt{(-7-1)^2+(-2-5)^2}$

=$\sqrt{(-8)^2+(-7)^2}$

=$\sqrt{64+49}$

=$\sqrt{113}$
