Mr. Ford wants to better understand the value of used cars over time. He reviewed some used-car ads and recorded the relationship between age and price in a table. Finally, he
calculated a line of best fit.
Used cars
Age in years (x) 3 6 4
2
6
Price (y) $15,000 $8,000 $12,000 $5,000 $19,000 $10,000
The equation for the line of best fit is y = -2,200x + 22,000.
Based on the equation, what estimates can you make about the used cars Mr. Ford reviewed?
Select all that apply.
They are worth roughly $2,200 less now than when they were new:
They likely had an average price around $22,000 when new.
They typically lose $2,200 of value per year.
At 5 years old, they had an average value of around $11,000.

1; 35 is the ratio

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
