The spine of a science textbook is 0.50 inches. How many science textbooks can be placed standing up on a shelf that is 12 inches long? Justify your answer with models, pictures, and/or equations.
equations.
Spine = width

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

but there’s no any figure there!

(x) - (y) = (1 + 4i)
