Question

Without graphing, classify each system as independent, dependent, or inconsistent. { -2x-y =9, 3x -4 =-8

Answer 1

When both equations are written in standard form, the coefficients and constants are different, so the system is {independent, consistent}.

`2x+y=-9\\3x=-4`

The same is true even if you mean

`2x+y=-9\\3x-4y=-8`
