Ordered Pairs, Reflections, and Area and Perimeter on the Coordinate Plane

Determine the perimeter of rectangle WXYZ.

(a)  

What is the y coordinate of a point that starts at $$\left(4.3,\ 7\right)$$  and is reflected across the x-axis?

What point is located on the y-axis?

Which sets of points are reflections over the y-axis?

$$\Delta ABC$$ Is reflected over x=2.

Plot the points for the reflection.

$$\Delta ABC$$ Is reflected over x=2.

What are the points for A' B' and C'?

$$\Delta ABC$$ Is reflected over x=2.

What are the points for A' B' and C'?

A' ​ (a)   B' ​ (b)   C' ​ (c)  

Complete the description.
$$\Delta A$$ was (a)   across the ​ (b)   then translaed ​ (c)   units to the​ (d)   to form $$\Delta C$$ .

Quadrilateral PRST is graphed on a coordinate grid. Quadrilateral PRST will be transformed using the rule $$\left(x,y\right)\rightarrow\left(-x,\ y\right)$$ to create quadrilateral P'R'S'T'. Which type of transformation occurred?

If triangle JKL is rotated 180 degrees about the origin, and then reflected over the y-axis, what are the new coordinates of J'?
