If you mean: y = x+4 then the perpendicular equation can be y = -0.5x+4
Without an equality sign the given expression can't be considered to be a straight line equation.
Without an equality sign the given expression is not an equation
If you mean y = x+2 then the equation of y = x+4 is parallel to it because they both have the same slope but with different y intercepts
y=x^3
Without a second independent equation, it's not a 'system' yet.
There isn't any. " yx-1 " is not an equation.
Without an equality sign the given expression can't be considered to be a straight line equation.
yx-3 is not an equation, and it has no graph.
Without an equality sign the given expression is not an equation
If you mean y = x+2 then the equation of y = x+4 is parallel to it because they both have the same slope but with different y intercepts
y=x^3
It generates a hyperbolic paraboloid.
Yes, xy is the same as yx, but should always be written as xy.
yx - 8 is an expression, not an equation nor an inequality. Consequently it cannot be graphed and so cannot have an intercept.
You can graph an equation or an inequality but you cannot graph an expression.
It would be y = 6x.
Without a second independent equation, it's not a 'system' yet.
