Let’s recap on these graphs. Are they your friends or foes? A)Straight Line : y = mx + c In the straight line equation: y = mx + c: 'x' and 'y' are the coordinates of the points that satisfy the function and so lie on the straight line graph. 'm' is the gradient of the straight line graph, and 'c' is the 'y intercept' of the straight line graph.
