PLEASE HELP 20 POINTS. ILL GIVE BRAINLIEST. One degree of longitude at the equator is approximately 111 km. As we move north or south the size of a degree changes. How many kilometers would 19 of longitude measure in kilometers at 45° latitude north?
A. 444 kilometers
B. zero kilometers
C. 222 kilometers
D. 55.5 kilometers

the answer to the question is a  

it has the same slope and the same y-intercept.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
