Question

Is y=2x-8 and 2x-y=8 a dependent independent or inconsistent

Answer 1

Note that 2x-y=8 can be solved for y:  y=2x-8.  This is identical to the first equation.  The graph of one is exactly the same as the graph of the other.  Thus, the two equations are dependent.

Answer 2

dependent

Explanation:

`y=2x-8` and
`2x-y=8`

First equation is already solve for y

LEts solve the second equation for y

`2x-y=8`

Subtract 2x on both sides

`-y=-2x+8`

Divide the whole equation by -1

`y=2x-8`

After solving for y, both equation are same

When both the system of equation are same then it has infinite solutions.

They are said to be dependent.
