Hello:

the equation is : y = ax+b

the slope is a : a * (2) = - 1 ... (perpendicular to a line with a slope of 2) because : 2x-y = 7 ... y=2x-7)

a = - 1/2 y = (-1/2) x+b ... (exemple : 1) y = - 1/2x + 6)

Which equation represents a line that is perpendicular to the line represented by 2x - y = 7?1) y = - 1/2x + 62) y = 1/2x + 63) - 2x + 64) y = 2x + 6
