+22 The chart shows the cost of a used car -- of a specific model and year -- at different total mileages. Using a graphing calculator, find the equation for the line of regression, the Pearson product-moment correlation value (r), and the predicted mileage for a used car when it costs $3000.
y = -0.010x + 160; r = -0.88; 130,000 miles
y = -0.017x + 325; r = -0.98; 274,000 miles
y = -0.027x + 345; r = -0.78; 264,000 miles
y = -0.037x + 375; r = -0.78; 264,000 miles

Thankyou!
XD!!
+129899 The correct answer is A.....
I generated the equation here : https://keisan.casio.com/exec/system/14059929550941
To get the predicted mileage when the car costs $3000 we have
-.010(3000) + 160 = 130 (thousand miles )
+193 y = -0.010x + 160; r = -0.88; 130,000 miles
Cphill you are the best
