Unformatted text preview: Ex : Decide whether the lines are ll, ⊥ , or neither. A) y= 1/3x+2 y= 3x7 ⊥ B) y=1/2x3 y=1/2x+3/2 ll Ex: decide whether the lines are ⊥ , ll, or neither. C) 4x+5y=2 5x+4y=3 5y=4x+2 4y=5x+3 y= 4/5x+2/5 y= 5/4x+3/4 Neither The slopes aren’t negative reciprocals! Ex : Line l has the eqn. y=2x+1. Line p is ⊥ to l and passes thru the pt (4,1). Write the eqn. for p . • Slope of l :2 • Slope of p :1/2 y=mx+b 1=(1/2)(4)+b 1= 2+b 3=b y=1/2x=3 Assignment Assignment...
