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
