Carter can line the books up on his bookshelf in 24 different ways.
The answer is nine because eighteen subtract nine is nine
Point/slope form is:-
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line
In the above diagram the slope is -1 and one point on the line is (0, -2) so we have:-
y - (-2) = -1(x - 0)
y + 2 = -x
x + y + 2 = 0 is the answer
