Graph the triangle shown is a pre-image. apply a scale factor of 1/2 to find the image of point a. (0, 0) (3, –2.5) (0, –2.5) (0, –10)

Correct choice is C

Step-by-step explanation:

A dilation by a factor with the center of dilation at origin has the rule:

If pre-image point A has coordinates (0,-5) (from the diagram), then the image point A' will have coordinates

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
