check please i pick the 3rd one
Select the equations that are parallel and perpendicular to y = x + 5 and that pass through the point (2, 1).
parallel: y = x  1
perpendicular: y = x + 2
parallel: y = x  1
perpendicular: y = x + 1
parallel: y = x + 1
perpendicular: y = x  3
parallel: y = 2x  2
perpendicular: y = 2x  1

Best ResponseYou've already chosen the best response.0perpendicular lines have slopes that are negatively reciprocal for this case the slope is 1. negative reciprocal of 1 is 1 With the general equation, y = mx + b. We know that the line has slope, 1 y = x + b Now substitute x = 2 and y = 1 1 =  (2) + b 1 = 2 + b b = 3 Final equation is y = x  3
