Question

A triangle with a vertex (−3, 5)
is translated up 6 units. What are the coordinates of this vertex after it is translated? Draw a graph if necessary.

Answer 1

Translating up 6 units adds 6 to the y-coordinate and leaves x unchanged.

(-3, 5) → (-3, 5 + 6) = (-3, 11).

So the vertex after translation is (-3, 11).
