Question

reflect point b over the dashed line. enter the new coordinates.
b = (?, )
point b coordinates: (1,4)

Explanation:

Step1: Identify given point and line

Point B: $(1,4)$, dashed line: $y=1$

Step2: Calculate vertical distance

Distance from B to line: $4 - 1 = 3$

Step3: Find reflected y-coordinate

Subtract distance from line: $1 - 3 = -2$

Step4: Keep x-coordinate unchanged

Reflected x-coordinate: $1$

Answer:

$B' = (1, -2)$
