Question

Find the distance between the two

points rounding to the nearest tenth (if necessary).
(-2, -2) and (0, 7)

Answer 1

Answer: L≈9.2 unit

Explanation:

(-2,-2) (0,7)

`L=√((x_2-x_1)^2+(y_2-y_1)^2)`

`x_1=-2\ \ \ \ \ x_2=0\ \ \ \ \ y_1=-2\ \ \ \ \ \ y_2=7`

Hence,

`L=√((0-(-2))^2+(7-(-2))^2) \\\\L=√((0+2)^2+(7+2)^2)\\\\L=√(2^2+9^2) \\\\L=√(4+81) \\\\L=√(85) \\\\L\approx9.2\ unit`
