Question

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.

Answer 1

Data:

• Originally ,sitting on the x-axis

,

• Julie ,lowered ,the whole picture

If the figure was sitting on the x-axis and the only change Julie made was lowering the whole figure, then the movement must have been made in the y-axis, and as it says lower, then is a subtraction. Counting how much the figure is below the x-axis, we can know 2 units were subtracted. Therefore...

Answer: b. Julie subtracted 2 from the y-term of each coordinate pair.
