first we need to find two point the same distance away from each equation

benice Group TitleBest ResponseYou've already chosen the best response.0
so the first point can the intersection of the two line s y=33x y=3x3 y=y 33x=3x3 6x=6 x=1 therefore y =0 (0,1) we just need one more point and then we make an equation for that line

ok so whats the next step to get the last point @benice

benice Group TitleBest ResponseYou've already chosen the best response.0
ok so we could pick say y =6 for both lines y=3x3 6=3x3 3x=9 x=3 (3,6) y=33x 6=33x 3=3x x=1 (dw:1332966561289:dw1,6)

so in my poor drawing we have two points on the lines... you need to find the midpoint of the line to get your second point

what is the formula to find the midpoint again @benice

so it would be (3+1) /2 ,( 6+6) /2 ?

princesskks Group TitleBest ResponseYou've already chosen the best response.0
and that is ( 1,6 ) the final answerr ? @benice ?

princesskks Group TitleBest ResponseYou've already chosen the best response.0
and then what do you do after that to solve the problem ?

benice Group TitleBest ResponseYou've already chosen the best response.0
remeber we need to find an equation that equal distance from both lines so we decide we would get two points (0,1) (1,6) now with these two points equal distance from both the lines this means they are on the line we are looking for so ,... how do the equation of the line with two points?

benice Group TitleBest ResponseYou've already chosen the best response.0
sorry the points are (1,0) (1,6)

ok so now we have what we need to find the locus ? @benice

benice Group TitleBest ResponseYou've already chosen the best response.0
yes find that line equation and your done
