11x - 3 = x - 13
-x -x
10x - 3 = -13
+13 +13
10x = 10
---- -----
10 10
x = 1
Answer: Multiplied by -1
Example:
Let's say we had the linear function y = 2x+5
Reflecting this over the y axis means we replace every x with -x and simplify
y = 2x+5 becomes y = 2(-x)+5 and that simplifies to y = -2x+5
The y intercept stays the same the whole time. This is because the y intercept is on the mirror line of the y axis. Stuff on the mirror line does not move.
Notice the jump from the old slope (2) to the new slope (-2) has us multiply by -1.
Answer: The man has 10$.

Answer:
C. The parent function will be moved to the right 4 units and down 5 units.
Step-by-step explanation:
A number added/subtracted inside the parentheses causes a horizontal shift in the opposite direction of the sign and a number added/subtracted outside the parentheses causes a vertical shift in the direction of the sign. Since a 4 is subtracted inside and a 5 is added outside The parent function will be moved to the right 4 units and up 5 units.
