Which of the following equations represents a line that is perpendicular to the line y = 4x + 5?

y = 4x - 5
y = -4x - 5
y = 1/4x - 5
y = -1/4x + 5

The correct answer is: y = -4x - 5

A line that is perpendicular to the line y = 4x + 5 will have a slope that is the negative reciprocal of 4. Option C and D have reciprocal slopes, but they are not negative. Option A has the correct negative slope, but it is not the reciprocal of 4. Option B has the correct negative slope of -4, making it the only equation that represents a line perpendicular to y = 4x + 5.
