A dilation has center (0, 0). Find the image of each point for the given scale factor.

pshichka [43]

Answer:

A. (−3,5)

Step-by-step explanation:

The rule for dilation by scale factor k is given by:

$(x,y)\to (kx,ky)$

The given point is P(-3,5) and the scale factor is k=1

We substitute the point and the scale factor into the rule to get:

$P(-3,5)\to P'(-3\times1,5\times1)$

This gives us:

$P(-3,5)\to P'(-3,5)$

The correct answer is A
