 Recall that
 lines never intersect. This is because they have the
 same
 and different
 If their y-intercepts were also the
 same, then the lines would
 and intersect everywhere. Lines that intersect
 to form right angles are called
 . When we constructed perpendicular lines,
 we
 the points of a line 90 degrees. This is how the
 angles were created. Algebraically, we say that the slopes are
 reciprocals meaning that their slopes have opposite
 and flipped
 You can check by multiplying them. The
 of negative
 reciprocals is -1.
