Answer:
see explanation
Step-by-step explanation:
Under a reflection in the line y = x
a point (x, y ) → (y, x ) , thus
(- 1, - 2 ) → (- 2, - 1 )
(1, 1 ) → (1, 1 )
(4, - 3 ) → (- 3, 4 )
Answer:
65/80 score
Step-by-step explanation:
Answer: (5.5, -4)
Step-by-step explanation:
You can use the midpoint formula to find the midpoint of point A and point B.
![M(\frac{x_{1}+x_{2} }{2}, \frac{y_{1} + y_{2} }{2})](https://tex.z-dn.net/?f=M%28%5Cfrac%7Bx_%7B1%7D%2Bx_%7B2%7D%20%7D%7B2%7D%2C%20%5Cfrac%7By_%7B1%7D%20%2B%20y_%7B2%7D%20%7D%7B2%7D%29)
x₁ = 8
x₂ = 3
y₁ = -7
y₂ = -1
