7. REINFORCE On the map, highways I-35 and 1-10 run perpendicular to each other. The distance between Allentown and Georgetown is 45 miles. The
distance between Georgetown and Masonville is 28 miles. The dashed line on
the map indicates a train track that connects Allentown and Masonville. What
is the distance (in miles) from Allentown to Masonville by train?

Step-by-step explanation:

no, because the sides are not congruent

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
