Which of the following lines are perpendicular to the line y=-1/2x+4

To determine which lines are perpendicular to the line y=-1/2x+4, we need to find the lines that have a slope that is the negative reciprocal of -1/2, which is 2.

The lines that are perpendicular to y=-1/2x+4 would have equations with a slope of 2.

Therefore, the lines that are perpendicular to y=-1/2x+4 are:

1. y = 2x + 1
2. y = 2x - 3
3. y = 2x + 5
