the answer should be figure B
this is because when x is 0, the cost of y is 15
(the +15 is called our initial amount it is when x is equal to zero)
from here if you multiply x by 2 the answer is 20 from our equation 10 times 2 is 20
add the 15 and now our y value is 35
this can be seen on that table when x is 2, the y is 35
