This is one of the hardest questions in the world, probably not to many people know the answer for this but I'm going to ask it... why can we swallow upside down?
the best answer will be brainiest person alive

we can swallow food upside-down because the movement of food occurs due to peristalsis and functions independently of gravity

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
