Answer:
Slope: m = 0
Equation: y = 3
Step-by-step explanation:
The equation of a line has the following format:

In which m is the slope.
We choose two points which the equation crosses.
I am going to choose (0,3) and (1,3)
(0,3)
When x = 0, y = 3. So



(1,3)
When x = 1, y = 3. So



Slope: m = 0
Equation: y = 3
20*5= 100
375+100=475
475/5= 95
Therefore the original price of a sweater is $95
Answer:
a=-2
Step-by-step explanation:
Let me know if you need the steps tho.
1 worker = 30 hours a week
1 worker = 30 x $5.50 a week = $165
1 worker = $165
1000 workers = 165 x 1000 = $165 000
