Guided Notes
Key concepts students will learn:
- •
A line is straight if the ratio of rise over run, also known as slope, is the same no matter where you measure it along the line.
- •
Parallel lines have the same slope and will never intersect, while perpendicular lines cross at a right angle and have slopes that are negative reciprocals of each other.
- •
Solving simultaneous equations involves finding the intersection point of two or more lines on a graph, which represents the values that make all equations true at the same time.
