Submarine a is positioned at –1,100 feet in relation to sea level. submarine b is positioned at –800 feet in relation to sea level. each submarine needs to be 200 feet below sea level in 30 minutes. which compares the speeds at which each submarine needs to travel?

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
