ANSWER
P'(6,-1)
EXPLANATION
The mapping for a reflection in the line y=x is
The line y=x is the mirror line for a function and it's inverse.
The x and y coordinates swap position.
The reflection of point P(−1, 6) across the line y = x is

Expected number of Daffodil when N = 150
First, we calculate the probability of having a Daffodil.
This gives:
Simplify
When there are 150 flowers, the prediction of Daffodils is:
Answer:
The system has infinitely many solutions.
(x, 1 - x, -3)
Explanation:
Writing the matrix in the form of a system of linear equations gives
Note that the third row does not give us any information on the values of x, y, and z.
Solving the first equation for y gives
Hence, the solution to the system is
Since x can take any value ranging from -∞ to ∞, the system has infinitely many solutions.
