Reading Solutions from Graphs

Inaccurate: Guessing coordinates roughly

Accurate: Use grid lines, zoom in, or use a ruler

Incomplete: Only finding one root of a quadratic

Complete: Look for all intersection points

Assumption: Not checking if answer makes sense

Verification: Always substitute back into original equation

Practice Questions for Graphical Solutions

A straight line y = 3x − 6 is plotted on a graph. Where does the solution to 3x − 6 = 0 appear on the graph?

A. Where the line crosses the y-axis
B. Where the line crosses the x-axis
C. At the origin
D. At the turning point of the line

Quick Recall Flashcards

Graphical Solution

Finding where two graphs intersect gives the solution to simultaneous equations

Intersection Point

The point where two graphs cross - this gives x and y values that satisfy both equations
