Question

Using technology we found the equation of the line to be y=-2x + 25. Using the given equation
predict the value of a car that is 3 and a half years old.

Answer 1

Answer:

A car that is 3 and a half years old would cost $18,000

Step-by-step explanation:

Using the given equation, $y=-2x+25$, we replace 'x' with '3.5' and solve for 'y'.

$y=-2(3.5)+25$

$y=-7+25$

$y=18$

Dollar values on the graph are expressed in thousands. Thus, we multiply 18 by 1,000 to get $18,000
