right/left/up/down

We have to work on the two coordinates separately.

The x coordinate changed from -4 to -2, which means that the point gained 2 units on the x axis, which in turn means that the point was shifted 2 units to the right.

The y coordinate didn't change, which means that the point is not moving vertically.

So, the point was moved by a translation of 2 units to the right.

were is the equation

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
