Lines1. For each line fill in your answers to the following questions in the table below: (Line E has been done for you.)

(i) Write down the coordinates (0; c) of the point of intersection of the line with the y-axis (the y intercept).

(ii) Choose two points on the line \((x_1;y_1), (x_2;y_2)\). Find the gradient of the line from the formula \( m=\frac{y_2-y_1)}{x_2-x_1)}\).

(iii) Use the values of c and m you have found to write the equation of the line in the form \(y = mx + c\).

2. What do you notice when you compare the equations of these lines?
