We know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
With the point 1 or the point 2 find the value of the constant k
Point 1 (-8,-6)
x=-8
y=-6
substitute
y/x=k
-6/-8=k
k= 3/4

therefore
the equation is
y= 3/4x
the answer is the option
y= 3/4x

If the diameter is 12 inches, the radius is 6 inches, because the radius is half the diameter.

Given the formula

A=\pi r^2

we have

A=36\pi

When you fold the circle in half, the resulting figure has half the area.

So, you start with a circle with area 36\pi

You fold it once and you have a semicircle with area 18\pi

You fold it twice and you have a quarter circle with area 9\pi
