Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
