Any line that goes from bottom left toward the top right of a coordinate plane.
I assume there are a missing + and =, that is the equation is either:3x + 5y = 53x = 5y + 5(though the first is the most likely).They are both the equation of a straight line.
If you mean: y = 2x and 2y = -x+4 then they are positive and negative straight line equations
A symetrical airfoil is an airfoil that has the same shape on both sides of its centerline and in this type of airfoil : the centerline is thus straight the chord line is the center line the maximum camber is zero the camber ratio is zero
The two equations represent the same straight line.
It is a straight line equation.
The straight line with no slope is a point
A straight line called light ray.
With the aid of a Tee square any type of straight line can be produced.
The symbol for a buzzer is a semi-circle with the straight line facing upwards and two prong type things sticking out the bottom of it.
The Sun, Moon and Earth are in a straight line.
