Question

On this graph I'm supposed to translate DEF 3 units horizontally , where do I plot the points?

​

Answer 1

D(0,5) F(-3, -4) E(4, -3)

Explanation:

3 units horizontally means that you should add 3 to each of the respective x coordinates. since D looks to be at (-3, 5) then you would make the new point (I'll call it D1) at D1 (-3 + 3, 5) or (0, 5). Do the same for all other points!

Answer 2

Hey there!
When you are translating something on a graph, things can get complicated. I'm here to help!

Translating 3 points horizontally means that every point on this triangle stated in this graph moves 3 points to the left or right, since horizontal means that. The problem doesn't reiterate whether a direction is included, so let's just worry about the right.

Moving 3 points to the right means that the x coordinate of the points gain 3.
D-> (-3, 5) -> Add 3 to the x coordinate -> D' -> (0, 5)
E-> (1, -3) -> Add 3 to the x coordinate -> E' -> (4, -3)
F-> (-6, -4) -> Add 3 to the x coordinate -> F' -> (-3, -4)

Note that the y-coordinate of the points remain unchanged and the altered translated points are labelled with the prime symbol, shown as ' which means that they are translated from the original graph.

Attached is the image that you should be getting when finished with your translations.

Hope this helped!
