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(69443) (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
