Find the coordinates of the vertices of the triangle after a translation of 1 unit right and 1 unit up
the coordinates are n(-2,-4), m(-3,-2), l(1,0)
a. n'(-2,-3), m'(-3,-1), l'(3,2)
b. n'(-1,-3), m'(-2,-1), l'(2,1)

It's b.  N'(-1,-3), M'(-2,-1), L'(2,1).

Step-by-step explanation:

One unit right and one unit up of the point (x, y) gives the new point

(x + 1), y + 1).

So  n(-2, -4) translates to (-2+1, - 3+1)

= N'(-1, -3).

M' and L' are calculated in the same way.
