What units are use for expressing rotational velocity

rads/s

Or radians per seconds

Explanation:

A

Rotational velocity is the rate of velocity at which an object or a particle is rotating around a center or a specific point in a given time period. It is also known as angular velocity. Rotational velocity is measured in angle per unit time or radians per second (rad/s). The rate of change of angular/rotational velocity is angular acceleration.

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
