To analyze the equation \(8x - 3y = 2x + 9y\), let's break down the statements provided:
-
8, −3, 2, and 9 are constants.
This is incorrect. These values are not constants; they are coefficients of the variables in the equation. -
8, negative 3, 2, and 9 are constants.
This is also incorrect for the same reason as the first statement. -
There are four variables.
This is incorrect. There are only two variables in the equation: \(x\) and \(y\). -
There are four variables.
This statement is identical to the previous one and is also incorrect for the same reason. -
8, −3, 2, and 9 are coefficients.
This statement is correct. In the equation, 8 is the coefficient of \(x\) in the term \(8x\), -3 is the coefficient of \(y\) in the term \(-3y\), 2 is the coefficient of \(x\) in \(2x\), and 9 is the coefficient of \(y\) in \(9y\). -
8 is the only factor of 8x.
This statement is misleading. While 8 is the coefficient of \(x\) in \(8x\), it is not the only factor (since \(x\) can also vary).
Therefore, the correct statement is: 8, −3, 2, and 9 are coefficients.
