Answer:
The rule or formula for the transformation of reflection across the line l with equation y = -x will be:
P(x, y) ⇒ P'(-y, -x)
Step-by-step explanation:
Considering the point

If we reflect a point
across the line
with equation
, the coordinates of the point P flips their places and the sign of the coordinates reverses.
Thus, the rule or formula for the transformation of reflection across the line l with equation y = -x will be:
P(x, y) ⇒ P'(-y, -x)
For example, if we reflect a point, let suppose A(1, 3), across the line
with equation
, the coordinates of point A flips their places and the sign of the coordinates reverses.
Hence,
A(1, 3) ⇒ A'(-3, -1)
Answer:
a) price markup $0.60
b) percent marked up 180%
Step-by-step explanation:
Amount marked up:
1.35 - 0.75 = $0.60
Percent markup:
0.75x = 1.35
x = 1.8 or 180%
