6-81.

Hannah thinks the solution to the system below is $(-4,-6)$. Wirt thinks the solution is $(20,10)$.  Homework Help ✎

$2x−3y=10$
$6y=4x−20$

1. Is Hannah correct?

Substitute Hannah's possible solution into the equation and see if it works.

1. Is Wirt correct?

Use the same process as (a).

1. What do the answers to (a) and (b) tell you about the lines in the problem?

If these ordered pairs satisfy both equations, what can we say about the lines?
