Answer:

-2 and 24

Step-by-step explanation:

the trend line is linear,

let the unknowns be A and B

hence the equation becomes

K = AJ + B

from the graph we can see the following:

when J = 0, K = 24 (substitute this into the equation)

K = AJ + B

24 = A(0) + B

24 =  B  (Answer)

Also notice that when K = 0, J = 12

together with our previous finding that B = 24, the equation becomes:

K = AJ + B

0 = A(12) + 24

12A = -24

A = -24 / 12

A = -2  (answer)
