Y= 2x+4, because when you plug in x and y you then solve for b and get 4. The 2x is the same because the slope stays the same on parallel lines.
Answer:
f=2
Step-by-step explanation:
3=9-3f
3-9=-3f
-6=-3f
2=f
f=2
For this case, what we must do is find the scale factor.
We have then that the scale factor is given by:

Where,
L1: side length of polygon ABCD
L2: side length of polygon PQRS
Note: both sides belong to the same side of each polygon
Substituting the values we have:

Rewriting we have:
Answer:
The scale factor of dilation is given by:
Some examples of perpendicular lines are the Interstate how it runs side by side with a median in the middle the roads are perpendicular because a lot of them will cross one another in a sharp turn trust me I know, Some more are the studs in the walls of your house, the wheels on your truck, the frame rails on your go cart just look around you if the lines intersect at a right angle then there perpendicular.
