A teacher graphs a linear equation on a coordinate grid When he graphs a second equation. It is the same line as the first equation. Which statement about the system of equations is true ? All values of x and y make both equations true
There are no values of x and y that make both equations true
if a value of x and a value of y make one equation true, the same values make the other equation true
if a value of x and a value of y make one equation true the same values make the other equation false
