In today’s mathematics lesson, teacher Ramona Galea discussed the topic of straight line graphs, emphasizing the importance of plotting coordinates accurately. The class reviewed a previous question where students were tasked with plotting the equations and identifying intersecting lines. The concept of gradient was introduced, explaining how it represents the steepness of a line, using the analogy of driving on different slopes. Students were reminded to think critically about the gradients when interpreting graphs, distinguishing between positive, negative, and zero gradients.
