Asystem of linear equations has infinitely many solutions. does that mean any ordered pair in the coordinate plane is a solution?
also, can you answer this, can you show algebraically that both equations, y=3x-3 and y=3(x-1) represent the same line? if so, explain how.

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
