Answer:
Slope -intercept for of equation 1: 
Slope -intercept for of equation 2: 
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
Step-by-step explanation:
We need to write equations in slope-intercept form.
The general formula of slope-intercept form is:
where m is slope and b is y-intercept.
The first equation is:

Slope-intercept form:

The second equation is: 
Rearranging: 
Slope-intercept form:

Slope -intercept for of equation 1: 
Slope -intercept for of equation 2: 
Looking at slope-intercept form of both equations, we have slope m = -2
Both have same slopes so, the lines are parallel.
They have different y-intercepts.

Range is the set of second numbers of the ordered pairs.
Answer:
210° , 330°
Step-by-step explanation:
using the sides of the 30- 60- 90 triangle
with legs 1,
and hypotenuse 2 , then
= 30° ← related acute angle
since
- 
then angle is in third / fourth quadrants , then required angles are
180° + 30° = 210° ← in third quadrant
360° - 30° = 330° ← in fourth quadrant
