Locus help plz Just started this unit and dont have a clue as to what is happening. Here is the question Describe the locus points that are 3 units from line y = 2x – 3. Give the equation of the locus. Draw a diagram as well. Well I did a rough sketch of the line given and moved left and right 3 units of that line and I think the equations of those lines are y=2x+9 and y=2x-3 but how do I describe the locus? I dont understand what to do now?
