Answer:
The slope is -1/4
Step-by-step explanation:
perpendicular line is 
To get the constant of proportionality (unit rate) you must find the miles driven in 1 hour. To get this you simply divide 200 by 4...
200÷4=50
So, the constant of proportionality is 50 mph.

Answer:
Absolute error is 0.05 cm.
Step-by-step explanation:
Given:
Actual length = 12.25 cm
Measured length = 12.2 cm
We need to find Absolute error.
Solution:
Now we can say that;
Absolute error is equal to measured length minus Actual actual.
framing in equation form we get;
Absolute error = 
Hence Absolute error is 0.05 cm.
