B is just a constant variable. In the standard form for the equation of a line y= ax +b. When x = 0, this is where we cross the y axis and the equation evaluates to b.
You cannot represent a proportional relationship using an equation.
That depends on what the equation is.
Not necessarily. The equation of a projectile, moving under constant acceleration (due to gravity) is a parabola - a non-linear equation.
Letters and symbols are used in equations to represent quantities, sometimes known or unknown. For example the symbol π (pi) represents the constant 3.14… and is unchanging. X or Y in an equation represent unknown terms that may vary depending on the equation, and other variables in the equation. There are numerous examples of both symbols and letters used in mathematical equations, but almost always they are either referring to a known constant term that is more simply expressed as a symbol, or an unknown or general term yet to be concretely determined.
y = cx where c is the constant of proportionality.
In a mathematial equation the letters wither represent a variable or a constant.
The solution is the answer to an equation.
B is just a constant variable. In the standard form for the equation of a line y= ax +b. When x = 0, this is where we cross the y axis and the equation evaluates to b.
A linear equation is when each term in the algebraic equation is either a constant or the product has a single variable and a constant.
You cannot represent a proportional relationship using an equation.
That depends on what the equation is.
It depends on the equation and the coefficient. Coefficients can be constant (Boltzmann constant, Avogadro's number) but they can also be variable (Reynolds number). The coefficient of gravity, g, is 9.81 m/s^2 in metric units on Earth.
In the equation E=mc^2, the letter c represents the speed of light in a vacuum. It is a constant value equal to approximately 299,792,458 meters per second.
In a periodic equation a triangle can be used to represent the given change of something.
If the equation is y = kx then the constant of proportionality is k.
Not necessarily. The equation of a projectile, moving under constant acceleration (due to gravity) is a parabola - a non-linear equation.
