Andy and Emily each go to a hardware store to buy wire. The table shows the cost y in dollars for X inches of the wire they need. Andy needs 21 feet of wire. Emily needs 14 yards of wire.

answer is c

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

because that’s us why

its   c, f, a
