Answer:
Suppose that during its flight, the elevation e (in feet) of a certain airplane and its time ... since takeoff, are related by a linear equation. Consider the graph of this equation, with time represented on the horizontal axis and elevation on the vertical axis. ... Unit 3; Linear Relationships Lesson 9: Slopes Don't Have to be Positive.
Step-by-step explanation:
hmmm units rates are just a matter of one above the other.
in this case is points/week.
9/15 points/weeks, we can just divide 9 ÷ 15 = 0.6, or 3/5.

6/3 = 6 divided by 3
= 2
12/6= 12 divided by 6
= 2
