Answer:
solid, plane
Step-by-step explanation:
A cross section is the intersection of a <em>solid</em> and a <em>plane</em>.
The form for that type of equation is y=|x-h|+k
H is the horizontal movement, k is the vertical.
So for your equation, y=|x-(-7)|+0
Final answer:
Move to the left 7 and up 0.
