Question 722497: I'm having with trouble with determiningwhether lines are parallel, perpendicular or neither when it comes to slopes.
For example:
y = 3x I know the slope is 3
-3x + y =2 i'm having trouble with this problem
This is what I have so far
-3x + Y = 2
Y = 3x + 2

You found enough to know how to read the slope in an equation of slope-intercept form. Whenever you are unsure, just convert the equation into slope-intercept form and read the slope.

"-3x + y =2 i'm having trouble with this problem -----"
-3x%2By-%28-3x%29=2-%28-3x%29
y=2%2B3x
y=3x%2B2, so what is the slope? What is the value of m corresponding to y=mx+b?
