Best ResponseYou've already chosen the best response.0We can use the distance formula mentioned bu chris00 is the last question the ditance from any point on the locus is 2 times bigger from the line 6x + 2y = 13 than it is from y = 3x + 8

Best ResponseYou've already chosen the best response.0writing them in the required form for the formula we hav 3x + y  6.5= 0 and 3x + y  8 = 0 so plugging these into the distance formulas and since one distance is twice the other; 3x + y  6.5 = 2 * (3x + y  8)   sqrt(3^2 + 1^2 ) sqrt (3^2 + 1^2) since the denominators are the same; 3x + y  6.5 = 6x + 2y  16 simplify this and you have the answer
