In today’s mathematics lesson, Ms. Ramona Galea focused on the topic of straight-line graphs. This is the fourth lesson in the series, where students learned how to plot straight-line graphs, understand gradients, and determine the y-intercept. Ms. Galea emphasized the importance of knowing that the equation of a line is in the form (y = mx + c), where (m) represents the gradient and (c) the y-intercept. Students were guided through examples to find gradients and y-intercepts, reinforcing that the y-intercept’s x-coordinate is always zero, and the lesson included tips for rearranging equations.
