Question

let L1 and L2  be the lines 3x-y=1 and x+y=2 respectively. find the point p on L2 such that PL1, the distance of p from L1, is 2.

Answer 1

yu need tu restrikt the quesshun more tu define how yu take the distans.

2 lines kros at x=1/4 & y=1.75. Go out along line 2 a short distans.

As long as yu dont go 2 far, the point will be 2 wotever from start point....

draw serkel with radius=2   from yer spot: it will hit other line at 2 plaeses, so distans tween lines=2.
