Question

Which algebraic rule describes the translation of ΔDEF to ΔD'E'F'?

Answer 1

Since the entire triangle is translated we can only refer to one point on the triangle, for example take point F(-1,3)

After Translation:

F'(-5,-4)

we subtracted 4 from the x value

we subtracted 7 from the y value

Answer:

(x,y) => (x-4,y-7)
