Answer:
(1,0) would be the correct answer.
Step-by-step explanation:
any point that is reflected across y=x will change unless it is on the line. if reflected across y=x, the coordinates will become y,x
Answer: x = -2, y = -10
Step-by-step explanation:
solve for x first in the equation -2x+3=7
-2x+3=7
-2x = 4
x = -2
now plug that x value into the other equation so we can find y
3x+1 = 5+y
3(-2)+1 = 5+y
-6+1 = 5+y
-5=5+y
-10 = y
