    Yes, so we want the point to be at 3/4*7 away from J horizontally 3/4*7 = ?

    Quick question if you don't mind me asking… do you think you could quickly show me how to find the y coordinate because I am not the best with ratios and I would really appreciate it if you showed me how?!! thanks @ganeshie8
