What is the function of polarized glasses?

a. to eliminate horizontally polarized light
b. to eliminate vertically polarized light
c. to allow all light
d. to block all polarized light

A.

Polarized glasses allow vertical light in, blocking horizontal light so that most of the glare is eliminated.

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

the answer is a)
