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 $\displaystyle y = mx + c$ (or $\displaystyle y = ax + b$)
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.
