Use the scatter plot of car resale values to answer the following question about making a prediction of the
resale value of a car.
Car Resale Values
100
80
60
LOR
Age of Car
Using the regression line, or line of best fit, predict the resale value of an 8-year-old car with an original cost of
$15,000.
a. The 8-year-old car could be worth approximately $2000.
b. The 8-year-old car could be worth approximately $5000.

step-by-step explanation:

in which figure is point g a centroid

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)

there are no multiple choices
