Answer:
Option 2. The scale factor is 2
Option 4. The center of dilation is at (-2,-1)
Step-by-step explanation:
I graphed it and points lined up at (-2,-1) and the side lengths doubled.
<u>ANSWER</u>

<u>EXPLANATION</u>
The given given equation is

We need to rewrite this equation in the slope-intercept form:

We add 3x to both sides.


We divide through by 2 to get,

The slope of this line is

Let the slope of the line perpendicular to this line be 'n' .
Then the product of the slopes of two perpendicular lines is always negative 1.




Therefore the slope of the new line is

Answer:


Step-by-step explanation:
Considering the system of the equations




Divide both sides by 2




















Im pretty sure number 15 is D
