Graph XY with endpoints X(−3, 1) and Y(4,−5) after the composition. Translation: (x, y)→(x, y+2) Rotation: 90° about the origin

Transformation involves changing the position of a point or line or shape.

See attachment for the graph of X"Y"

The endpoints are given as:

A translation of means that:

A 90 degrees rotation about the origin is:

So, we have:

X’ is (3,3) and Y’ is (-3,-4)

Step-by-step explanation:

Here, we want to get the coordinates of the point XY after translation and rotation about the origin at 90 degrees

X (-3, 1 ) and Y (4,-5)

Using the translation we have

(-3, 1 + 2) and (4, -5 + 2)

= (-3,3) and (4 , -3)

Rotation about the origin, we have

(x , y) = (y , -x)

So the new set of points will be:

(3,3) and (-3, -4)

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180
