Answer:
y = - 6x - 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 6x + 2 ← is in slope- intercept form
with slope m = - 6
Parallel lines have equal slopes then
y = - 6x + c ← is the partial equation
To find c substitute (- 2, - 3 ) into the partial equation
- 3 = 12 + c ⇒ c = - 3 - 12 = - 15
y = - 6x - 15 ← equation of parallel line
Answer:
a) cluster sampling
Step-by-step explanation:
In cluster sampling method, each member of a population is assigned to one and only one group.This means clusters are formed through probability method usually a simple random sampling.The participants in the clusters are the only one to be surveyed.
In this example, simple random sampling is used to identify 12 home rooms(cluster) where a group of 20 students (participants) in each room is given the survey.
Let the frequency be 'f' and wavelength be 'w'
, 
w= 100 m and f = 3,000 kilohertz
Plug in the above values to find k
3000 = 
To find k, multiply both side by 100
3000(100) = k
k = 300,000
So equation becomes,
w= ? f = 500 kilohertz
500 = 
w = 
w = 600 m
