Page 1: Steps for Graphical Method
The first page outlines the initial steps for solving systems of equations graphically.
Highlight: The graphical method involves transforming equations and plotting lines to find their intersection.
Step 1: Transform each equation to y = ax + b form
- Example: 2x + 2y = -6 becomes y = -x - 3
- Example: 10x - 5y = 30 becomes y = 2x - 6
Step 2: Calculate characteristic points for each line
- Find x and y intercepts or other easily calculated points
Step 3: Plot both lines on a coordinate system
- Use the calculated points to accurately draw each line
Example: For y = -x - 3, points −1,−2 and 0,−3 are plotted
Example: For y = 2x - 6, points 0,−6 and 3,0 are plotted
The page includes a graph showing both lines plotted, with the point of intersection visible.
