Apart of the graph representing an electrical signal is shown. the voltage first rises steadily from an initial value (a) till a maximum value (b) and then drops instantly till to the initial voltage (at c) and this repeats, such that || and and are vertical. if a = (1, 1) and b = (4, 3) respectively, then what is the equation of ? -3y – 2x = 5 3y – 2x = 5 3y – 2x = 5 3y + 2x = 5
