Answer:
y = 2x - 20
Step-by-step explanation:
equation: y = mx + b
plug in slope
y = (2)x + b
plug in (x, y)
-8 = 2(6) + b
multiply
-8 = 12 + b
subtract
-20 = b
plug in b
y = 2x - 20
Answer:
x=2y+8
y=
x-4

Answer:
A. 2.3km
Step-by-step explanation:
Since 2cm = 1km
4.6cm = xkm
xkm = 4.6 x 1 / 2
= 2.3km
When 36 people are seated the room is 2/3 full.
So for 1/3 , 18 people are needed
It will be 3/3 full if 54 people are present
So there can be 54 people in total
Now for the room to be 1/2 full , people will be 1/2 x 54 = 27 people
