Answer:
see below
Step-by-step explanation:
Number of workers (x) 0 10 20 30 40 50 60 70 80 90
Number of units (y) 2 52 102 152 202 252 302 352 402 452
Part A
There is a correlation
For each increase of 10 in x, there is an increase of 50 in y
10 10 10 10 10 10 10 10 10
Number of workers (x) 0 10 20 30 40 50 60 70 80 90
Number of units (y) 2 52 102 152 202 252 302 352 402 452
50 50 50 50 50 50 50 50 50
Part B
m = (y2-y1)/(x2-x1)
= (452-402) /( 90-80) = 50/10 = 5
The y intercept is the value of y when x =0
The y intercept is 2
The slope intercept form of the the line is
y = mx+b
y = 5x+2
PartC
The y intercept is that we start with 2 of the units and for each worker gained, they will make 5 units per day
