A statistics student is studying if there is a relationship Using the computer output, what is the correlation? between the price of a used car and the number of

miles it had been driven. She collects data for 20 cars

0-0.82

of the same model with different mileage and

-0.68

determines each car's price using a used car website. 0.68

The analysis is given in the computer output.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

i think the answer is b. i hope i !
