The line  y=−x+1  is drawn on the coordinate plane. It is translated 1 unit to the right and 2 units up. What is the equation of the translated line?(1 point)Responsesy=−x+4y equals negative x plus 4y=x+3y equals x plus 3y=x+4y equals x plus 4y=3

1 answer

To translate the line \( y = -x + 1 \) 1 unit to the right and 2 units up, we can follow these steps:

  1. Translate 1 unit to the right:

    • When you translate a line to the right, you adjust the x-coordinate by subtracting 1.
    • Substituting \( x - 1 \) into the equation gives: \[ y = - (x - 1) + 1 = -x + 1 + 1 = -x + 2 \]
  2. Translate 2 units up:

    • When you translate a line up, you add 2 to the y-coordinate.
    • Therefore, the equation becomes: \[ y = -x + 2 + 2 = -x + 4 \]

The equation of the translated line is: \[ y = -x + 4 \]

Thus, the correct response is \( y = -x + 4 \).
