Thread: Help With Project

Very lost with a project in math class.
Need to find out and show work to see of this system is parallel, perpendicular or neither?

x-3y=-5
y=3x-9

Any Help on how to find this out?

You should know that an equation in the form (or )

has the gradient as m and y-intercept as c.

If the gradient of the two lines are the same, then they are parallel.
If their product gives -1, it means they are perpendicular.
If they are neither the same, nor their product gives -1, then they are neither parallel nor perpendicular.
