I NEED HELP PLEASE! :)

Answer:

Perpendicular

Step-by-step explanation:

To tell if the lines are perpendicular/parallel, you must look at the slope, but in this case, you must first get y by itself, like so:

3x + 7y = 15

-3x - 3x

___________

7y = -3x + 15

Divide both sides by 7:

y = $\frac{-3}{7}x + \frac{15}{7}$

Now the other equation:

7x - 3y = 6

-7x -7x

_________

-3y = -7x + 6

Divide both sides by -3:

y = $\frac{7}{3} x - 2$

You can see that the lines are perpendicular because the slopes ( $\frac{-3}{7} x$ and $\frac{7}{3}$ ) are opposite reciprocals.
