Graph the Constant-Profit Lines Through (3, 2) and (5, 3)

Graph the constant-profit lines through (3, 2) and (5, 3) . Use a straightedge to identify the corner point(s) where the
maximum profit occurs for the given objective function.
-P = 5x + y

A) Max P = 45 at x = 9 and y = 0, at x = 8 and y = 4, and at every point on the line segment joining the preceding two points.
B) Max P = 44 at x = 8 and y = 4, at x = 0 and y = 12, and at every point on the line segment joining the preceding two points.
C) Max P = 44 at x = 8 and y = 4
D) Max P = 45 at x = 9 and y = 0
