Answer:
C) y=-(1/4)x+40
The price of a car that had been driven 56 thousand kilometers is estimated as $27,500
Step-by-step explanation:
In the figure attached, the plot is shown. y represents price (thousands of dollars) and x represents kilometers driven (in thousands)
The y-intercept of the trend line is located at (0, 40)
The line also pass through (20, 35), then its slope is: (35 - 40)/(20 - 0) = -1/4
Replacing into the equation with x = 56, we get:
y=-(1/4)(50)+40 = 27.5
that is, 27.5*1000 = $27,500
