Question

Which matrix represents the image of the triangle with vertices at (-2, 0), (1, 5), and (4, -8) translated 4 units left and 3 units up?

Answer 1

a \[[2, 5, 8 ,-3, 2, -11]\] b\[[8,-4,-16,0,15,-24]\] c\[[-6,-3,0,3,8,-5]\] d\[[-6,-3,0,-3,2,-11]\]

Answer 2

It's going from black to blue:

Then, EACH POINT is moving from blue to green:

So...graph one point. Move it left 4 places, up 3 places.
