I am a four-sided shape I have four right angles and my sides are not all equal to each other what shape am I ​

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Whats the name of the vertical axis

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10
