The bottom line of the tent above was originally sitting on the x-axis. Julie lowered the whole picture by changing the coordinate pair at each vertex and connecting the points. What changes did Julie make?aJulie subtracted 2 from the x-term of each coordinate pair.bJulie subtracted 2 from the y-term of each coordinate pair.cJulie subtracted 2 from both the x-term and the y-term of each coordinate pair.dJulie added 2 to the y-term of each coordinate pair.
