Please help me with this both for 25 points

A 20

B The constant is $4/ square ft

Step-by-step explanation:

We can find the slope of the cooking time versus weight by

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

   = (50-30)/( 2.5-1.5)

   = 20/1

The constant is the slope which is 20

For the second problem, we also need to find the slope

We have points, (0,0) and (250,1000)

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

 = ( 1000-0)/(250-0)

 1000/250

  4

The constant is $4/ square ft

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
