Question

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)
Responses

y=x+4
y equals x plus 4

y=3
y equals 3

y=x+3
y equals x plus 3

y=−x+4

Answer 1

y = −x + 4

Reason: For a point (x0,y0) on y = −x + 1, the translated point is (x0+1, y0+2). Let x = x0+1, y = y0+2; then y−2 = −(x−1)+1 = −x+2, so y = −x+4.
