To determine whether y = 2x - 1 is a linear equation, we need to check if its degree is 1.
The degree of a polynomial equation is the highest power of the variable. In this case, the variable is x.
The equation y = 2x - 1 only has x raised to the power of 1, since it appears as 2x. There are no x^2, x^3, or any higher powers.
Since the highest power is 1, the equation y = 2x - 1 is indeed a linear equation.
To write it in standard form, we need to rearrange the equation to have the variables on one side and the constant term on the other side. The standard form of a linear equation is Ax + By = C, where A, B, and C are constants.
In the given equation y = 2x - 1, we have y on one side and 2x - 1 on the other side. We can rewrite it as -2x + y = -1.
Therefore, the linear equation y = 2x - 1 can be written in standard form as -2x + y = -1.
