Question

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)​

Answer 1

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

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.
