124.95 + 7% tax = 124.95 * 1.07 = $133.70
Plus $10 = $143.70 <--- answer to part 1
Part 2
143.70 / 15 = 9.58

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).

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the y axis
We have the following points:

We find the slope:

Thus, the equation is of the form:

We substitute a point and find b:

Finally, the equation is:

Answer:

0.07 - 2.69 = -2.62
