Answer:
D) Jump
Step-by-step explanation:
Instead of explaining why D is right, I will explain why A, B, and C are wrong.
A) Speed does not apply to graphs unless that is the x or y value.
B) Constant slopes only apply to linear graphs, in which the only change would be a constant one.
C) An increase is not the proper term for this.
This only leaves D.
A jump is like when a graph has the points,
(1,1)
(2,2)
(3,3)
(4,6)
(5,7)
(6,8)
