Question

A point A is translated in the coordinate plane three units to the left and nine units upward to produce its
image point A'. Which of the following represents the length of segment AA'?

Answer 1

Answer:

im sorry if this is wrong but i think number 4

Step-by-step explanation:

Answer 2

The length of segment AA' will be "3√10 units".

By using the distance formula,

→ $d = \sqrt{(y_2-y_1)^2+ (x_2-x^2)^2}$

the,

By substituting the values,

→ $AA' = \sqrt{(3-0)^2+(9-0)^2}$

           $= \sqrt{(3)^2+(9)^2}$

           $= \sqrt{9+81}$

           $= \sqrt{90}$

           $= 3\sqrt{10} \ units$

Thus the answer above i.e., "Option 3" is right.
