Which of the following rules best describes the matrix below? (Picture)
2 answers:
Answer:
The correct option is b.
Step-by-step explanation:
The rule of rotation of 90° counterclockwise about the origin is defined by the matrix

The rule of reflection of the line y=x is defined by the matrix

The rule of rotation of 180° about the origin is defined by the matrix

The rule of translation of 1 unit left and 1 unit up is defined by the matrix

Only the rule of reflection of the line y=x is defined by the given matrix, therefore the correct option is b.
Answer:
option b
reflection over the line y = x

Answer:
x=3 and y=12
Step-by-step explanation:
equation:1
equation:2
Solving equation:1 for 'y' in terms of x
equation:3
Putting 'y' in equation:2 which will make the equation of the single variable


Putting value of 'x' in equation:3 to find 'y'
