Need help determining the slope of the line and y - intercept with units for both slope and y - intercept of both equations: A(sub 405) = (e)(l)

Need help determining the slope of the line and y - intercept with units for both slope and y - intercept of both equations:

A(sub 405) = (e)(l) ([NP]) + y -intercept ----------------------Beer Lambert Law

equation on the graph absorbance measurements - 405nm (y -axis) vs NP Concentration - M (x - axis)

equation 1: y = 1734.1x + 0.0225

equation 2: y = 4543.1x + 0.0423
