The first one is D because you would divide for amount each day, and the second one is A because that has the correct expression of division.
Lets calculate how much is a dozen bagels, if 4 cost $30 then, each is:
each bagel = 30/4 = $7.50
now you pay $7.50 with a $10 bill, so you receive $2.50 the remainder of the subtraction! :)
First, you should rearrange your equation using simple algebra
2x-3y-18=0
2x-18=3y
(2x/3)-6=y
the y intercept has an x coordinate of 0, so substitute 0 as x in your equation to find the y-int.
the x intercept has a y coordinate of 0, so substitute 0 as y in your equation and algebraically solve for the x-int
to make the table of values, just substitute different values in for x in the equation
