 Question 514184: in the x-y plane, the equation y=1/2x-3 is a line that is perpendicualr to the graph of the equation y=mx+(1/3). what is the value of m?Found 2 solutions by Alan3354, Maths68:Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!m = the negative inverse of 1/2 m = -2 Answer by Maths68(1474)   (Show Source): You can put this solution on YOUR website!y=1/2x-3 ...........(1) y=mx+(1/3)...........(2) Compare (1) with the Equation of the straight line standard form y=1/2x-3 ...........(1) y=mx+b m=(1/2), b=-3 When two lines are perpendicular the multiplication of the their slopes result in (-1) So the slope of the other line will be = m = -2
