What will be the y - coordinate of b' if ab is dilated by a factor of 2/5, centered at origin?

When the dilation of a line or is centered at the origin, both the x and y coordinates are multiplied by the same value, k (which represents the scale or ratio of dilation)

If ab is dilated by a factor of 2/5 to produce a’b’, then k = 2/5

Since the dilation is centered at origin,

The y-coordinate of b' what will be 2/5 of the y-coordinate of b.

i am unable to solve this problem

step-by-step explanation:

if you was gonna solve for a, a is a   < -12
