Question 599512: 3x-8y=-10
32x+12y=19
Are these solutions parallel, perpindicular or neither

You can put this solution on YOUR website! 3x-8y=-10
32x+12y=19
Are these solutions parallel, perpindicular or neither
-------------------
Those are equations, not solutions.
The lines made when the equations are graphed might be parallel, etc.
-----
Find the slope of each line by solving for y
3x-8y=-10 --> y = (3/8)x + something
32x+12y=19 --> y = (-8/3)x + something
---
The coefficient of x is the slope, m
If the slopes are negative inverses, they're perpendicular, which these are.
---
The "something" doesn't affect the slope, only the position of the line.
