She owes him $0.75 because if she paid him $1.50 already you just subtract that from $2.25
Since y must equal both 3x+2 and x-4, we deduce that 3x+2 and x-4 must equal each other. So, we have

Answer:
Option (3)
Step-by-step explanation:
Perpendicular lines: Perpendicular lines are the lines that intersect each other at right angles
Intersecting lines: Intersecting lines are the lines that intersect each other at a point to form angles but vertically opposite angles are equal
Hence , from above conclusion we can write Perpendicular lines must cross to form ninety degree angles, but intersecting lines cross to form angles of varying measures.
Hence , Option (3) is correct answer
