Is (5,2) a solution of 4x-2y=-6

Question

I said no, am I right?

I am working on another problem where they want to know if this system of equations is perpendicular or parallel or neither, I said neither. Is this right?

I am to solve by using elimination: 2x+3y=1, 4x+6y=2
I keep getting o, no solution. What am I doing wrong?

Answer 1

5x+4y=2, 4x-5y=4....I said neither on whether the line was parallel or perpendicular or neither.
