Urgently answer, right triangle trignometry

So for this you will be doing proportions. Your equation will look like this:

Firstly, cross multiply:

Next, square root both sides of the equation, and your answer should be

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

graph of this function as shown below:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
