Objective:

To graph linear equations using intercepts.

Vocabulary:

Notes:

Use this graphing method for linear equations that are written in standard form (Ax + By = C).

Steps to graph using intercepts:
  1. Find the x-intercept:
    • Set y = 0 (substitute 0 for y), and solve for x.
  2. Find the y-intercept:
    • Set x = 0 (substitute 0 for x), and solve for y.
  3. Plot the two intercepts.
  4. Use a straight edge to draw a line through the points
  5. Add arrows to the ends and label the line

Examples:

Find the intercepts then graph each equation.
