Question

Determine if the lines are parallel, perpendicular or neither. Show all work.

x - 5y = 30 and 10y = 2x + 90

Answer 1

The lines are parallel

Explanation:

Answer 2

Explanation:

Put the equations into slope-intercept form.

x-5y = 30 ⇒ y = ⅕x - 6

10y = 2x + 90 ⇒ y = ⅕x + 9

Both lines have slope = ⅕, so the lines are parallel.
