Use the start and end point of the line.
(0, 4000) and (10,0)
Slope = change in y over the change in x
Slope = 0-4000 / 10-0
Slope = -4000/10
Slope = -400
The answer is A
Answer:
a
Step-by-step explanation:
tangent gives the value of slope
tan=y/x
4000/10=400
Since the direction of the line is left, there is minus before the slope value.
