Straight Line Graphs

It covers the key form 𝑦 = 𝑚 𝑥 + 𝑐 y=mx+c, exploring gradient and y-intercept, and how these relate to the graphical representation of linear equations. Students are guided through identifying gradients, rearranging equations into standard form, and interpreting graphs. The lesson includes a variety of worked examples and practice questions that support skills such as finding gradients between two points, calculating midpoints, determining intercepts, and forming equations of lines from given information. It also extends to important concepts like parallel and perpendicular lines, including how to prove relationships between them.
