Question

What is an equation of the image of the line y = {x - 4after a dilation of a scale factor of centered at theorigin?

Answer 1

We have the following function given:

$y=x-4$

We want to apply a dilation with a scale factor k centered at the origin

Assuming that the scale factor is k, then we just need to do the following :

$y\text{ = x}-(4\cdot k)$

And with this we preserve the condition of centered at the origin and with the dilation factor
