Determine if the Lines are Parallel, Perpendicular or Neither Given the Equations

TL;DR

By comparing slopes of equations written in y=mx+b form, determine if lines are parallel, perpendicular, or neither.

Transcript

in this problem we're given two lines and we're being asked to determine if the lines are parallel perpendicular or neither it's kind of an interesting problem so solution so the way we'll determine this is to solve each of these equations for y and then we'll compare the slopes so the goal step one is to write them both in the form y equals mx plu...

Key Insights

• 💁‍♂️ Expressing equations in y=mx+b form aids in comparing slopes effectively.
• 🫥 Slopes are crucial in determining if lines are parallel, perpendicular, or neither.
• 🫥 Parallel lines have equal slopes, while perpendicular lines have negative reciprocal slopes.
• 🏙️ The process involves isolating y, comparing slopes, and applying the definitions of parallel and perpendicular lines.
• 🍉 Shortcut methods like dividing every term by a coefficient can simplify rewriting equations.
• 🫥 Understanding the slope's role in line relationships clarifies the concepts of parallel and perpendicular lines.
• 😵 Cross-checking slopes by reciprocating and changing signs helps confirm perpendicularity.

Summary & Key Takeaways

• Two lines are given, each in the form x=6y-3 and 3x+1/2y.

• The equations are rewritten in y=mx+b form by isolating y.

• By comparing the slopes, it is determined if the lines are parallel, perpendicular, or neither.
