Answer:

Correct option is

(0, 0)

Form the graph, we can see that solution is (0,0).

The point of intersection of lines y = 3x and x = 3y must satisfies both the equation.

From the options (0,0) satisfies both the equations, hence the point of intersection of given lines is at origin i.e. (0,0).

$Volume=\frac{8}{27}\ cubic\ yard$

Step-by-step explanation:

Let V be the volume of hay in each stack

Given:

Length of the each stack is $\frac{2}{3}\ yard$

And Jay stores hay in cubic stacks on his farm.

The volume of the cone is.

$Volume\ of\ cone = (side)^{3}$

Now, we substitute value of length of stack in above equation.

$V=(\frac{2}{3})^{3}$

$V=\frac{2^{3}}{3^{3}}$

$V=\frac{8}{27}\ cubic\ yard$

Therefore, the volume of hay in each stack is $V=\frac{8}{27}\ cubic\ yard$

Answer:

y=4x-14

Step-by-step explanation:

m=(10-2)/(6-4)

m=8/2

m=4

y-y1=m(x-x1)

y-2=4(x-4)

y=4x-16+2

y=4x-14
