Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)
m = 
= 
, thus
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 3, 2), then
2 = - 
+ c ⇒ c = 
y = x + → C
Using the given linear function, the formula underestimates the median weekly earnings in 2013 by $3.
<h3>What is the linear function for the estimate?</h3>
The function that estimates the median weekly earnings n years after 1980 is given by:
W = 13n + 231.
2013 is 2013-1980 = 33 years after 2000, hence the estimate is given by:
W = 13 x 33 + 231 = 660.
Since 657 < 660, the formula underestimates the median weekly earnings in 2013 by $3.
