Parallel Lines Have the same ( ).
Are y=3x + 4 and y=3x parallel lines?
Are y=-2x -1 and y=2x + 4 parallel lines?
Write the equation of a line that is parallel to the line y=-½x + 3.

/slopesPerpendicular Lines • have negative reciprocal slopes.• You flip the slope and change the sign.
What slope is perpendicular to the slope of:
a) 3
b) 2/5
c) -7
d) 0
• A slope of 3/2 has a perpendicular slope of - 2/3. • A slope of -3 has a perp slope of 1/3.
