Answer:
Option (C)
Step-by-step explanation:
From the given table,
Dependent variable is the weight of each load and independent variable is number of loads of crushed stones.
Let the equation that represents the total weight is,
W = mn + b
Where 'm' = slope of the line
b = y-intercept
n = number of loads
Since graph starts from the origin (0, 0), y - intercept 'b' will be 0.
Two points lying on the line are (0, 0) and (1, 2000)
Slope of the line 'm' =
=
=2000
Therefore, equation will be,
W = 2000n
Option (C) will be the answer.
