What is the image of A(8,2) under R90
1 answer:
(-2,8) is the image point of A(8,2)
<h3>What is Rotation ?</h3>A rotation is a type of transformation which takes each point in a figure and rotates it a certain number of degrees around a given point.
As we know , the rule for rotation of is given by :-
(x,y)⇒(-y,x)
In the above formula (x,y) is the point of pre-image and (-y,x) is a point of image.
Since ,given point of pre-image : A(8,2)
After the rotation of , the image point are :-
(8,2) ⇒ (-2,8)
Therefore,
The image point of A(8,2) is (-2,8) .

Part c) The constant of proportionality of Savannah's wage is
Step-by-step explanation:
See the attached figure to better understand the problem
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
To find out the constant of proportionality k , divide the variable y (total earned) by the variable x (number of hours)
<em>Kevin's wage</em>
Take any point from the table
I take the point (2,16.50)
<em>Greg's wage</em>
Take any point from the table
I take the point (3,27.00)
<em>Savannah's wage</em>
Take any point from the table
I take the point (2,19.00)
