The field between two charged parallel plates is kept constant. If the two plates are brought closer together, the potential difference between the two plates The field between two charged parallel plates is kept constant. If the two plates are brought closer together, the potential difference between the two plates .a. Increases. b. Decreases. c. Does not change.

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
