The Straight Line Graph 2 Wall Chart is a comprehensive mathematics learning resource designed to teach learners how to determine the x intercept and y intercept of straight line equations. Using clear worked examples, colour coded sections, and supporting graphs, this educational wall chart simplifies one of the most important concepts in coordinate geometry and algebra. It is an ideal classroom reference for intermediate and senior phase learners, as well as high school mathematics students preparing for tests and examinations.

The wall chart is divided into two main worked examples. The first example demonstrates how to find the intercepts of the equation 5x - 2y = 6. Learners are guided step by step through the process of finding the y intercept by substituting x = 0, and then calculating the x intercept by letting y = 0. Each calculation is clearly presented, with the resulting coordinates displayed before showing the completed straight line graph with both intercepts plotted.

The second section explains the same method using the equation y = -4x + 1/2. Students follow detailed calculations for determining both intercepts and then see how these values are represented on the coordinate plane. The accompanying graph reinforces the relationship between algebraic equations and their graphical representations, helping learners visualise how intercepts define a straight line.

This educational poster encourages mathematical understanding by combining algebraic calculations with visual graphing techniques. Its logical layout allows students to quickly compare different equation formats while reinforcing the universal method of setting x = 0 to find the y intercept and y = 0 to find the x intercept. The chart serves as an excellent classroom display, tutoring aid, revision guide, or homeschool resource for improving confidence in coordinate geometry, linear equations, graph interpretation, and problem solving.
