Question

Distance between (6,1) and (2,-7))

Answer 1

Distance formula:

Distance = sqrt((x2-x1)^2 + (y2-y1)^2)

Distance = sqrt((2-6)^2 + (-7 -1) ^2)

Exact Distance = 4 sqrt(5)

As a decimal = 8.944

Answer 2

Answer:

6.3 units

Step-by-step explanation:

use distance formula:  d = $\sqrt{(y-y)^2 + (x-x)^2}$

d = $\sqrt{(1-(-7))^2 + (6-2)^2}$

d = $\sqrt{8^2 + 4^2}$

d = $\sqrt{64+16}$

d = $\sqrt{80}$

d = $\sqrt{4 * 10}$

d = 2$\sqrt{10}$ ≈ 6.3
