What must be true about slopes of parallel lines?
They are the same
Solve for x
x5=610

If you are struggling to find the LCD of your fractions, what can you do to find another denominator that will work.
Multiply the denominators together. This will give you a common denom. Just might not be the LOWEST.
What is 24 equivalent to?
2*2*2*2 = 16
(x + 1)(x + 2)
What is x2+3x+2
What must be true about slopes of perpendicular lines? Must use correct vocabulary!
They are OPPOSITE RECIPROCALS
