Here, we want to interpret the meaning of the slope
The slope generally refers to the change in y values with corresponding change in x value
with respect to this question, we can see that the slope is negative
What this mean is that the rate of change in the level of oxygen measured in liters is decreasing with an increase in the time
This means that as more time elapses, more oxygen is used up leading to a decrease in the liters of oxygen present
Train A: Speed of 60 mph. (1 mile per minute)
Train B: Speed of 90 mph. (1.5 miles per minute)
after 2 hours: (2:00)
Train A has gone 120 miles. (half-way mark)
Train B has gone 0 miles.
Hour 2:48: (2:48)
Train A has gone 168 miles.
Train B has gone 72 miles.
72 ----><---------------168
At 2:48 P.M the two will meet. 72+168=240
I hope this helps! :)

Answer:
D. -4
Step-by-step explanation:
the slope formula is
m=(y2-y1)/(x2-x1)
(x2,y2) = (4,7)
(x1, y1) = (5,3)
So (7-3)/(4-5) = 4/-1 = -4
