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
P'(6,-1)
Answer: 5.044 0z is not pineapple juice
Step-by-step explanation:
total amount of mixed fruit juice: 6.45 oz (oz stands for ounce)
pineapple juice: 1.406 oz
total - pineapple juice=not pineapple juice
6.45 - 1.406=5.044 oz
Hope this helps!! :)
Please let me know if you have any questions
A(-1,3), B(-2,5)
Slope equation : (y₂-y₁) / (x₂-x₁)
Plug in the values into the equation.
AB = (5 - 3) / (-2+1)
Simplify.
AB = 2 / -1
AB = -2
So, your slope is -2.
