If lines p and q are reflected across the x-axis, then which of the pairs of lines shown would coincide with this transformation? 5 pairs of parallel lines. Lines p and q are parallel with p passing through zero, 4 and negative 4, zero and q passing through zero, 6 and negative 6, zero. Lines a and b are parallel to lines p and q Lines c and d are vertical. Lines e and f are parallel with e passing through negative 6, zero and zero, negative 6and f passing through negative 4, zeroand zero, negative 4. A lines a and b B lines c and d C lines f and e D lines g and h
