### Hint

What do we need to have true for the lines to be perpendicular?

What would it mean for the equation of a line to pass through a given coordinate?

What would it mean for the equation of a line to pass through a given coordinate?

### Answer

One possible answer:

y=2/8x+6

4x+1y=5

(3,-7)

y=2/8x+6

4x+1y=5

(3,-7)

Another possible solution is:

y=(1/2)x+7

6x+3y=9

(4,-5)
