Question

Which of these is closest to the unit distance between points M and M' ?

Answer 1

the coordinate of M is (-3, -5)

it is given that M is translated 6 unit right , and 5 unit up.

so the coordinate of M' is (-3+6 , -5 + 5) = (3, 0)

so, the distance between M and M' is,

`d=\sqrt[]{(3-(-3))^2+(0-(-5))^2}`
`\begin{gathered} d=\sqrt[]{6^2+5^2} \\ d=\sqrt[]{36+25} \\ d=\sqrt[]{61} \end{gathered}`

d = 7.81

so, the closest to the unit distance is 8

thus, the answer is option D
