Graph ​ y−5=−2/3(x+9)​.<br> plot two different points. please show work i am very lost. thank you

Y -:5 = 2/3x + 6 because 6 is 2/3 of 9
add 5 to both sides
y - 5 +:5 = 2/3x + 6 + 5
y = 2/3x + 11
the y intersept is 11 or (0 , 11) when x is 0
when x is 3
y = 2/3 (3) + 11 or 2 + 11 = 13
so a 2nd point could be (3 , 13)

The kind of transformation the quadrilateral underwent is 180° rotation about the origin and the new vertex of Q is (4,5).

<h3>What is transformation of plane shapes?</h3>

Transformation is the change in the coordinates of the vertices that make up a plane shape.

This can be done either by translation, reflection or rotation.

Analysis:

since the x and y coordinates of P is the opposite of the coordinates of p' then there is a 180° rotation about the origin.

If vertex Q is (-4, -5), then Q' is the opposite which is (4, 5 )

In conclusion, the transformation is a 180° rotation and the coordinates of Q' are (4, 5).
