If: x-y = 4 and x-3y = 4 Then by solving the simultaneous equations: x = 4 and y = 0 So the lines intersect at (4, 0) which will be a vertical straight line
If the slope of the equations are the same then they are parallel If the slope of the equations are minus reciprocal then they are perpendicular If the slope of the equations are different then they are neither
x = 4 and y = 7 which will satisfy both equations
(4, -7)
The lines are perpendicular.

+ (plus) - (minus) / (divide) * (multiply) ^ (power) = (equals)

{-1,-2}
No.
They are identities because they are true for ALL values of w and x.
(4, -7)
The lines are perpendicular.
