2x + 5y = 8

5x + 2y = 1
Are the line parrallel, perpendicular, or neither the answer I got was parrallel someone please help me if I am wrong.

Find the domain of the function

solve both of the equations for y if the slopes are recipricals of one another the lines are perpendicular otherwise if they are the same slope they are parallel
which expression is equivalent to 3x + 2y - 8 - 5x + y
