The equation of a straight line is a fundamental concept in mathematics that helps describe linear relationships. Y = mx + c forms the basis for understanding straight line graphs and their properties.
• The equation consists of two main components: the gradient (m) which determines the steepness and direction, and the y-intercept (c) which indicates where the line crosses the y-axis
• Key methods include calculating gradients using two points, finding equations using the point-slope form, and interpreting graphs
• Essential skills covered include working with coordinates, understanding slope calculations, and manipulating algebraic equations
