Based on the items produced, and the profit yielded from those items, the best model to represent the data is y = -1.026x² + 1,016.402x - 162,075.
<h3>Which model shows the profit and items produced best?</h3><h3 />You can find this out by testing the models using the items produced (independent or "x" value) to see if the model produces a close enough y value.
Assuming x is 100:
= -1.026x² + 1,016.402x - 162,075
= (-1.026 x 100²) + (1,016.402 x 100) - 162,075
= -$70,694.80
Assuming x is 400:
= -1.026x² + 1,016.402x - 162,075.
= (-1.026 x 400²) + (1,016.402 x 400) - 162,075.
= $80,325.80
These figures are very close to the actual y values given which makes this the best model.

Answer:
The y-intercept of the line is the point (0,-41)
Step-by-step explanation:
we have the points
(-36,-117),(-27,-98) and (-18,-79)
step 1
Find the slope of the linear equation
The formula to calculate the slope between two points is equal to
take the points
(-27,-98) and (-18,-79)
substitute the values
step 2
Find the equation of the line in point slope form
we have
substitute
----> equation in point slope form
step 3
Convert the equation in slope intercept form
where
m is the slope
b is the y-coordinate of the y-intercept
isolate the variable y
therefore
The y-intercept of the line is the point (0,-41)
