A triangle has coordinates A (1, 5), B (-2, 1) and C (0, -4). What are the new coordinates if the triangle is dilated with a scale factor of 1/5?

myininaya (myininaya):

multiply by 1/5

myininaya (myininaya):

I will give you a formula Say one of the coordinates given were (x,y) above and you were asked to dilate the object by a scale factor of d, then the new point after dilation would be (dx,dy) dx means d times x dy means d times y

myininaya (myininaya):

So you can apply what I just said to all 3 points?
