A rectangle with the vertices (3, -2), (3, -4), (7, -2), (7, -4) is reflected across the x-axis and the rotated 90 degrees count

irga5000 [103]

Answer:

The new vertices are: $(-2,3),(-4,3),(-2,7),(-4,7)$

Step-by-step explanation:

The given vertices are $(3,-2),(3,-4),(7,-2),(7,-4)$

Rule for reflection about x axis is $(x,y)$ → $(x,-y)$ .

So, $(3,-2)$ → $(3,2)$

$(3,-4)$ → $(3,4)$

$(7,-2)$ → $(7,2)$

$(7,-4)$ → $(7,4)$

Now, new vertices after reflection about x axis are $(3,2),(3,4),(7,2),(7,4)$ .

Rule for 90 degree rotation counter-clockwise is $(x,y)$ → $(-y,x)$ .

So, $(3,2)$ → $(-2,3)$

$(3,4)$ → $(-4,3)$

$(7,2)$ → $(-2,7)$

$(7,4)$ → $(-4,7)$

Therefore, the new rectangle after reflection about x axis and rotated 90 degrees counter-clockwise has the following vertices:

$(-2,3),(-4,3),(-2,7),(-4,7)$
