Consider the system of equations shown below y= -5x + 1 y= -5x +10. When graphed, the system consists of two lines that will never meet, no matter how far they are extended. Why are the lines parallel? The linear equations have the same slope and y-intercept. The linear equations have different slopes and y-intercepts. The linear equations have the same slope b-intut different y-intercepts. The linear equations have different slopes but the same y-intercept.
