Which equation represents a line that is perpendicular to the line represented by 2x-y=7?

The equation that represents a line that is perpendicular to the line is y = -1/2x + 7

The standard equation of a line is expressed as y = mx + b

where:

The slope of the line perpendicular is M = -1/m

Given the equastion 2x - y = 7. This can be written as:

-y = -2x - 7

y = 2x + 7

The slope the perpendicular lins M is -1/2

Hence the equation that represents a line that is perpendicular to the line is y = -1/2x + 7
