Part of the graph representing an electrical signal is shown. the voltage rises steadily from an initial value (a) to a maximum value (b). it then drops instantly to the initial value (c) and repeats such that || and and are vertical. if a = (1, 1) and b = (4, 3), what is the equation of ?

a.
-3y − 2x = 5
b.
3y − 2x = 5
c.
3y − 2x = -5
d.
3y + 2x = 5
