Help

Step-by-step explanation:

m<2=49° (vertically opposite angles are equal)

m3=112° (vertically opposite angles are equal)

m1= 112°+ m1 =180 (the sum of interior angles measure 180°)

hence, m1 = 180 - 112°

m1= 68°

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
